# Changelog
## [1.37.0.0] - 2026-05-14
## **Split-engine gbrain: remote MCP for brain, local PGLite for code.**
## **Symbol-aware code search now coexists with cross-machine knowledge.**
Path 4 (Remote MCP) setup gets a new opt-in at Step 4.5: a tiny local PGLite (~30s, ~120 MB) for `gbrain code-def`, `code-refs`, `code-callers` per worktree. The remote brain keeps holding artifacts, transcripts, and cross-machine queries. The two engines stay independent. Transcripts route to the artifacts repo on remote-MCP machines, the brain admin's pull job indexes them, and the local PGLite stays code-only with no transcript pollution. A new `gbrain_local_status` field on `gstack-gbrain-detect` distinguishes ok / no-cli / missing-config / broken-config / broken-db; `/sync-gbrain` and the sync orchestrator both gate on it so a dead Postgres URL gives a clear remediation message instead of two stages of ERR output.
`/setup-gbrain` Step 1.5 (new) detects a broken local engine on re-run and offers four options: Retry the probe, Switch to PGLite (one-way, .bak rollback on failure), Switch brain mode (fall through to Step 2's path picker), or Quit. `/sync-gbrain` Step 1.5 (new) STOPs cleanly on broken-config / broken-db with a remediation message and SKIPs code+memory in `missing-config + remote-http` so the brain-sync push to the artifacts repo still runs.
### The numbers that matter
Source: `bun test test/gbrain-local-status.test.ts test/gbrain-detect-shape.test.ts test/gbrain-sync-skip.test.ts test/gbrain-init-rollback.test.ts test/gstack-upgrade-migration-v1_37_0_0.test.ts` — 5 new gate-tier test files, 27 cases, all green in ~5s. Periodic-tier E2E `test/skill-e2e-setup-gbrain-path4-local-pglite.test.ts` runs the full Path 4 + Step 4.5 Yes flow against a stub MCP and passes in 280s.
| Surface | Before | After |
|---|---|---|
| Path 4 + `/sync-gbrain --full` output (Garry's broken-db state) | `ERR code source registration failed: gbrain not configured (run /setup-gbrain)` + `ERR memory gbrain import exited 1: Cannot connect to database` | `SKIP code skipped — local engine broken-db — config points at unreachable DB; see /setup-gbrain Step 1.5` + brain-sync runs normally |
| `bin/gstack-gbrain-detect` runtime | bash + jq, single-purpose probe | TypeScript shebang script sharing the `localEngineStatus()` classifier with the orchestrator. 10 JSON fields, 9 existing keys byte-compat; one new `gbrain_local_status` enum. Memoized resolvers cut ~400ms of duplicate fork-exec per skill preamble. |
| Status probe cost | `gbrain doctor --json` without `--fast` could hang up to 5s on dead DB | `gbrain doctor --json --fast` (3s ceiling) + DB-reachability via `gbrain sources list --json` stderr classification (~80ms steady), 60s TTL cache keyed on `{HOME, PATH, gbrain bin, gbrain version, config mtime}` |
| Path 4 user discovers code search | Hidden — only `/sync-gbrain` errors hint at it | `/gstack-upgrade` migration v1.37.0.0 prints a one-time notice when `gbrain_mcp_mode == remote-http` AND `gbrain_local_status == missing-config`. `gstack-config set local_code_index_offered true` to silence. |
| Transcripts indexed in remote brain | Local-only `gbrain import` writes to the LOCAL engine, polluting PGLite if user opts into Step 4.5 | `gstack-memory-ingest` detects remote-http MCP, persists staged markdown to `~/.gstack/transcripts/run-<pid>-<ts>/` instead of tmpdir, skips local `gbrain import`. `bin/gstack-brain-sync` allowlist now covers `transcripts/run-*/*.md`; brain admin pulls and indexes. |
### Itemized changes
#### Added
- `lib/gbrain-local-status.ts` — shared 5-state engine status classifier (`ok` / `no-cli` / `missing-config` / `broken-config` / `broken-db`) with 60s TTL cache and `--no-cache` flag. Probes via `gbrain sources list --json` + stderr classification reusing the exact patterns from `lib/gbrain-sources.ts:66-67`.
- `/setup-gbrain` Step 1.5 — broken-db remediation with 4 options (Retry / Switch to PGLite / Switch brain mode / Quit). PGLite switch is rollback-safe: `mv ~/.gbrain/config.json` to a timestamped `.bak`, `gbrain init --pglite`, on non-zero exit restore the .bak verbatim.
- `/setup-gbrain` Step 4.5 — Path 4 opt-in for local PGLite code search. Yes path runs `gstack-gbrain-install` (idempotent) + `gbrain init --pglite --json` with the same rollback semantics. No path keeps Path 4 as remote-MCP-only.
- `/sync-gbrain` Step 1.5 — pre-flight local engine status check. STOPs on broken-config / broken-db with remediation, SKIPs code+memory in `missing-config + remote-http` so brain-sync still runs.
- `gstack-upgrade/migrations/v1.37.0.0.sh` — one-time discoverability notice for existing Path 4 users whose machine has no local engine yet.
- `bin/gstack-brain-sync` allowlist — `transcripts/run-*/*.md` so remote-MCP transcripts persisted to `~/.gstack/transcripts/` reach the artifacts repo.
- New test files (gate-tier, all mocked, no real gbrain): `gbrain-local-status.test.ts` (11 cases), `gbrain-detect-shape.test.ts` (8 cases), `gbrain-sync-skip.test.ts` (5 cases), `gbrain-init-rollback.test.ts` (3 cases), `gstack-upgrade-migration-v1_37_0_0.test.ts` (5 cases).
- Periodic-tier E2E `skill-e2e-setup-gbrain-path4-local-pglite.test.ts` for the full Path 4 + Step 4.5 Yes flow.
#### Changed
- `bin/gstack-gbrain-detect` — rewritten bash → TypeScript shebang script. Filename unchanged so existing skill preamble callers shell out without edits. 9 existing JSON fields preserve name + type + semantics; new `gbrain_local_status` field added. Documented dependency: requires `bun` on PATH (the gstack installer already provides this).
- `bin/gstack-gbrain-sync.ts``runCodeImport()` + `runMemoryIngest()` return `{ran: false, summary: "skipped — local engine <status>; remote MCP unaffected"}` when `localEngineStatus() != 'ok'`. Brain-sync stage continues regardless.
- `bin/gstack-memory-ingest.ts` — when `gbrain_mcp_mode === 'remote-http'`, persists staged transcripts to `~/.gstack/transcripts/run-<pid>-<ts>/` and skips local `gbrain import` entirely.
- `bin/gstack-artifacts-init` — extends the managed `.brain-allowlist` to include `transcripts/run-*/*.md` and `transcripts/run-*/**/*.md` (privacy class: behavioral).
- `sync-gbrain/SKILL.md.tmpl` Step 1 — corrects misleading prose about memory stage "routing through MCP." Memory stage always shells out to local `gbrain import`; in remote-http mode it persists markdown instead.
#### Fixed
- Pre-existing flake in `test/gstack-next-version.test.ts` — bumped per-test timeout from default 5s to 15s. Spawned `gstack-next-version` CLI takes 4-5s wall time on M-series Macs under suite load and tipped over 5001ms intermittently.
#### For contributors
- New shared classifier pattern: `lib/gbrain-local-status.ts` exports `localEngineStatus()`, `resolveGbrainBin()`, `readGbrainVersion()`. The latter two are memoized per-process keyed on PATH so detect + classifier share fork-exec results.
- 13 architectural decisions captured in plan file `~/.claude/plans/the-real-product-fix-squishy-galaxy.md` — including Codex outside-voice findings (4 became structural decisions: keep proactive setup question, route transcripts via artifacts repo, SKIP+brain-sync on broken engine, retry-first repair menu).
## [1.35.0.0] - 2026-05-13
## **Docs become a tracked surface, not an afterthought. `/document-generate` writes them from scratch, `/document-release` audits coverage in four Diataxis quadrants.**
## **Every PR now ships a coverage map of what got documented vs what shipped. New skill generates tutorials, how-tos, references, and explanations from code. Both speak the same vocabulary, so gaps become visible in the PR body instead of accumulating silently.**
You can now run `/document-generate` to write missing documentation from scratch. The skill reads your code first (the codebase archaeology step is non-skippable), maps the public surface, then writes docs in the four Diataxis quadrants: tutorial (newcomer walkthrough), how-to (task-oriented), reference (factual API description), explanation (design rationale). It runs standalone or chains automatically from `/document-release` when the coverage map finds gaps. `/document-release` got a Step 1.5 coverage map that scores every new entity across the four quadrants. Items with zero coverage show up as critical gaps in the PR body. Items with reference-only coverage show up as common gaps. Architecture diagrams get scanned for entity-name drift against the diff. The CHANGELOG voice check now uses a 0-3 sell-test rubric: 1 point each for "what changed?", "why care?", and "how to use it?". Entries below 2 get rewritten.
A new section in CLAUDE.md documents the fork-PR workflow for `garrytan-agents` PRs: push the branch to `garrytan/gstack` and re-target so eval CI can access secrets. The pattern keeps secret distribution scoped to one branch instead of broadening it to all forks.
### The numbers that matter
Source: this PR's diff against `origin/main` and the new skill template at `document-generate/SKILL.md.tmpl`.
| Surface | Before | After |
|---------|--------|-------|
| Doc-generation skills | 1 (`/document-release`) | 2 (`/document-generate` + enhanced `/document-release`) |
| Diataxis quadrants surfaced in PR body | 0 | 4 (tutorial / how-to / reference / explanation) |
| `/document-release` workflow steps | 9 | 9 + new Step 1.5 (coverage map) |
| CHANGELOG voice scoring | gut-check ("would a user think 'oh nice'?") | 0-3 rubric (3 = reference + explanation + how-to all present) |
| Architecture diagram drift detection | none | scans ARCHITECTURE.md against diff for renamed/removed entities |
| Doc-debt visibility in PR | none | `### Documentation Debt` subsection with critical + common gaps per Diataxis quadrant |
`/document-generate` is 446 lines of new template producing a 1184-line generated SKILL.md. The Diataxis vocabulary makes "did docs get updated?" a visible answer instead of an implicit one.
### What this means for downstream gstack users
You stop guessing whether your docs are complete. When you ship a new skill, `/document-release` shows you which quadrants you covered and which you skipped, and the gaps land in the PR body where reviewers see them. When you want to bootstrap docs for an existing project, `/document-generate` walks you from zero to four-quadrant coverage in one session. Diataxis becomes the shared vocabulary across `/ship`, `/document-release`, `/document-generate`, and whatever skill comes next that needs to know whether you have a tutorial.
To use: run `/document-release` after `/ship` (or let `/ship` auto-invoke it), see the coverage map in the PR body, then run `/document-generate` if it flags critical gaps.
### Itemized changes
#### Added
- **`/document-generate` skill** (`document-generate/SKILL.md.tmpl`, 446 lines): Diataxis-based documentation generator with 9-step workflow — scope, codebase archaeology, partition, reference, explanation, how-to, tutorial, cross-linking, quality self-review. Reads the full codebase before writing a single line of docs.
- **`/document-release` Step 1.5 — Coverage Map**: scans diff for new public surface (skills, CLI flags, config options, API endpoints), classifies each entity by Diataxis quadrant coverage, flags zero-coverage items as critical gaps and reference-only as common gaps. Output feeds the PR body.
- **`/document-release` Architecture diagram drift detection**: extracts entity names from ASCII/Mermaid blocks in ARCHITECTURE.md, cross-references against the diff, flags renamed/removed entities.
- **`/document-release` `### Documentation Debt` section in PR body**: surfaces critical gaps, common gaps, and stale diagrams with a one-line description + Diataxis quadrant per item. Suggests adding a `docs-debt` label.
- **`/document-release` CHANGELOG sell-test rubric**: 0-3 scoring per entry (1 point each for reference / explanation / how-to coverage). Entries below 2 get rewritten.
- **Skill routing entry**: `/document-generate` added to `SKILL.md` routing rules and `README.md` skills table (Technical Writer category).
- **CLAUDE.md fork-PR workflow section**: documents how to handle "check out <PR link>" when the PR is from a non-collaborator fork. Push the branch to `garrytan/gstack`, close the fork PR, open a new PR from the base-repo branch. Keeps secret distribution scoped.
#### Changed
- `/document-release` description and triggers updated to reference the coverage map and `/document-generate` chaining.
- README.md skills table grouping: `/document-release` and `/document-generate` now appear under the Technical Writer category.
#### For contributors
- `document-generate/SKILL.md` is generated from `document-generate/SKILL.md.tmpl`. Do not edit the `.md` directly. Run `bun run gen:skill-docs` after template edits.
- `gstack/llms.txt` now lists `/document-generate` (auto-regenerated from the skill template).
## [1.34.2.0] - 2026-05-13
## **Three filed bugs land in one PR. `/codex review`, `/investigate` learnings, and `/sync-gbrain` engine detection all work again.**
## **One CLI bump broke `/codex review`. One forgotten allowlist silently dropped years of investigation history. One stacking pair of bugs no-op'd `/sync-gbrain` for every Supabase user. All three are fixed with regression tests that lock the patterns in.**
`/codex review` died the day Codex CLI 0.130.0 shipped. The new CLI made `[PROMPT]` and `--base <branch>` mutually exclusive, and Step 2A had always passed both, so every review call exited before talking to a model. Fix: bare `codex review --base` for the default case, `codex exec` with a tempfile-backed prompt and DIFF_START/DIFF_END delimiters for the `/codex review <focus>` case. The exec route preserves the filesystem boundary instruction; the bare route ships without it because Codex 0.130 has no documented system-prompt config key, and the skill files those instructions guarded are public. Custom-instructions reviews now also defend against prompt injection from adversarial diff content (the delimiter pattern tells the model where data ends and instructions resume).
`/investigate` told the agent to log learnings with `type: "investigation"`, but `bin/gstack-learnings-log:22` rejected anything not in `[pattern, pitfall, preference, architecture, tool, operational]`. Every investigation run since the type was introduced wrote a stderr message and exited 1, silently to the user because nothing checked the exit code. Years of root-cause findings went nowhere. One-line fix: add `investigation` to `ALLOWED_TYPES`.
`/sync-gbrain` returned `engine: "unknown"` for every Supabase user on gbrain ≥ 0.25. Two stacking bugs. `execSync("gbrain doctor --json --fast 2>/dev/null")` threw on non-zero exit (gbrain doctor exits 1 whenever `health_score < 100`, which is essentially every fresh install due to `resolver_health` warnings), so the JSON output never reached the parser. And gbrain ≥ 0.25 dropped the top-level `engine` field from doctor output anyway. The fix recovers stdout from the thrown error object and falls back to reading `~/.gbrain/config.json` (respecting `GBRAIN_HOME`) when doctor doesn't surface an engine. Also moves the call from `execSync` to `execFileSync` so the shell redirect isn't a Windows-portability footgun, and adds error logging to `~/.gstack/.gbrain-errors.jsonl` so future parse failures are visible.
### The numbers that matter
Source: `bun test test/gstack-memory-helpers.test.ts test/learnings.test.ts test/codex-hardening.test.ts` (75 tests, 149 expect calls, 26 seconds) plus repo-relative smoke-tests against Codex CLI 0.130.0 and synthetic gbrain configs in temp `GBRAIN_HOME`.
| Bug | Before | After |
|---|---|---|
| `/codex review` on Codex CLI 0.130.0 | `error: the argument '[PROMPT]' cannot be used with '--base <BRANCH>'`, every call dies | Bare review works; `/codex review <focus>` routes through `codex exec` with DIFF_START/END markers |
| `/codex review <focus>` prompt injection surface | Diff content interpolated into prompt with no data/instructions boundary | DIFF_START/DIFF_END delimiters plus tempfile pattern, explicit "treat as data" instruction to the model |
| `/investigate` learning persistence | Exit 1 to stderr, no log written, invisible to user | Exit 0, learning appended, future sessions see prior root-cause findings |
| `/sync-gbrain` engine on gbrain ≥ 0.25 + Supabase | `engine=unknown`, all sync stages skip silently | Resolves to `supabase` via doctor stdout recovery or `~/.gbrain/config.json` fallback |
| Test isolation when running on a developer's real config | Tests read real `~/.gbrain/config.json`, pass-or-fail by reviewer's machine | Tests set `HOME` + `GBRAIN_HOME` + `PATH` to temp dirs, deterministic |
| Codex template regression guard | None, the broken state shipped to main | Static test asserts no `codex review` line combines a quoted prompt with `--base`, across both `.tmpl` source AND generated `SKILL.md` |
### What this means for builders
If you have been seeing `/codex review` fail on argv parsing since Codex CLI hit 0.130.0, run `/gstack-upgrade` to pick this up. If you ran `/investigate` between the type's introduction and this release, your learnings were dropped (they exit-1'd to stderr only, so there is nothing to recover), but going forward every investigation's root-cause finding is logged and retrievable. If you use gbrain with a Supabase backend and `/sync-gbrain` has been quietly doing nothing, this release brings it back. The three reporters (`Stashub` on #1428, `diogolealassis` on #1423, `Shiv @shivasymbl` on #1415) each filed a clean repro, and in Shiv's case shipped a tested patch. Credit where it is due.
### Itemized changes
#### Fixed
- **`codex/SKILL.md.tmpl` Step 2A** — replaced the unconditional `codex review "$boundary" --base <base>` invocation with a two-path branch. Default (no custom user instructions): bare `codex review --base <base>`. Custom instructions: `codex exec -s read-only "$(cat $_PROMPT_FILE)"` where `$_PROMPT_FILE` contains the filesystem boundary, the user's focus, and the diff between `DIFF_START` / `DIFF_END` markers. Probed `-c 'system_prompt="..."'` against Codex 0.130; the key isn't documented and silently no-ops, so the bare path ships without a re-injected boundary. Skill files under `.claude/` and `agents/` are public, so this is token efficiency, not safety. Contributed report by `Stashub` on #1428.
- **`bin/gstack-learnings-log`** — added `'investigation'` to `ALLOWED_TYPES` (was: `[pattern, pitfall, preference, architecture, tool, operational]`). Updated the usage comment to list valid types. Contributed report by `diogolealassis` on #1423.
- **`lib/gstack-memory-helpers.ts`** — rewrote `freshDetectEngineTier`. Three changes: switched `execSync` to `execFileSync` to drop the bash-specific `2>/dev/null` shell redirect (portable to Windows); recover stdout from the thrown error object so non-zero exits from `gbrain doctor` don't lose the JSON; fall back to reading `gbrain` config (respecting `$GBRAIN_HOME`, defaulting to `~/.gbrain/config.json`) when doctor output doesn't surface an `engine` field. Added `logGbrainError` helper that appends one-line JSONL to `~/.gstack/.gbrain-errors.jsonl` on parse failure. Patch shape contributed by `Shiv @shivasymbl` on #1415; tested against gstack v1.31.0.0 + gbrain v0.31.3 + Supabase.
#### Added
- **`test/gstack-memory-helpers.test.ts`** — `detectEngineTier` regression test for the schema_version:2 fallback path. Sets `HOME`, `GSTACK_HOME`, `GBRAIN_HOME`, and `PATH` to temp dirs (so the test doesn't read the developer's real `~/.gbrain/config.json` or invoke a real `gbrain`), writes a synthetic `{"engine":"postgres","database_url":"..."}` to the temp `GBRAIN_HOME`, asserts `detectEngineTier()` returns `engine: "supabase"`. The existing `detectEngineTier` `beforeEach`/`afterAll` blocks were also extended to isolate `HOME` and `GBRAIN_HOME`, closing a flake source where the prior tests would read whatever was on the reviewer's machine.
- **`test/learnings.test.ts`** — two tests for the `investigation` type. One round-trips `gstack-learnings-log` with `type: "investigation"` and asserts the file gets the entry. The other reads `investigate/SKILL.md.tmpl` and asserts it emits `"type":"investigation"` verbatim, caller contract guard against the template drifting to an invalid type.
- **`test/codex-hardening.test.ts`** — two tests applied to BOTH `codex/SKILL.md.tmpl` AND the generated `codex/SKILL.md`. The first parses Step 2A's section and asserts no `codex review` invocation line combines a quoted-prompt or variable positional argument with `--base`. The second asserts that Step 2A still contains either bare `codex review --base` OR `codex exec`, guards against accidentally deleting both fix paths in a future edit.
#### For contributors
- The probe for `-c 'system_prompt="..."'` support in Codex 0.130 lives in the plan, not the codebase. If a future Codex release exposes a real system-prompt config key, re-injecting the filesystem boundary in bare `codex review --base` is a 3-line follow-up patch to `codex/SKILL.md.tmpl`.
- The "supabase" engine tier means "remote postgres" in practice. Gbrain config uses `engine: "postgres"` for both real Supabase and local-postgres-for-testing, and `freshDetectEngineTier` maps both to `"supabase"` because downstream sync code treats them identically. The label compression is documented inline.

## Checking out PRs from garrytan-agents
When the user says "check out <PR link>" and the PR is from `garrytan-agents/gstack`
(or any other fork that is NOT a collaborator on `garrytan/gstack`), do NOT just
`gh pr checkout`. Fork PRs don't receive base-repo secrets (`ANTHROPIC_API_KEY`,
`OPENAI_API_KEY`, etc.), so the eval/E2E CI jobs fail with empty-env auth errors
regardless of what's set on the base repo.
**Workflow:** push the branch to `garrytan/gstack` (the base repo) and re-target
the PR from there.
Concretely, after `gh pr checkout <N>`:
1. Note the original PR number and head branch name.
2. Push the same branch to the base repo: `git push origin HEAD:<branch-name>`
(origin = `garrytan/gstack`, since the worktree is set up with that remote).
3. Close the fork PR (`gh pr close <N> --comment "moving to base-repo branch for secret access"`).
4. Open a new PR from the base-repo branch: `gh pr create --base main --head <branch-name>`.
5. New PR's workflows will get secrets automatically.
Why not fix it on the fork side? `garrytan-agents` isn't a collaborator on
`garrytan/gstack`. Adding it as a collaborator (option A) or flipping the
repo-wide "send secrets to fork PRs" toggle (option B) would let secrets reach
fork PRs from anyone — broader blast radius than just moving this one branch.
Option C (this section) keeps secret-distribution scope tight.
If the user asks you to skip the move (e.g., "just leave it as a fork PR"),
respect that — eval CI will fail with empty-env auth, but check-freshness,
workflow-lint, and windows-tests will still pass on the fork PR.

/**
* gstack-gbrain-detect — emit current gbrain/gstack-brain state as JSON.
*
* Rewritten from bash to TypeScript in v{X.Y.Z.0} to share the engine-status
* classifier with bin/gstack-gbrain-sync.ts. Single source of truth via
* lib/gbrain-local-status.ts. Filename and exec semantics unchanged: callers
* just shell out to the file path; the bun shebang resolves at runtime.
*
* Output (always valid JSON, even when every check is false):
* {
* "gbrain_on_path": true|false,
* "gbrain_version": "0.18.2" | null,
* "gbrain_config_exists": true|false,
* "gbrain_engine": "pglite"|"postgres" | null,
* "gbrain_doctor_ok": true|false,
* "gbrain_mcp_mode": "local-stdio"|"remote-http"|"none",
* "gstack_brain_sync_mode": "off"|"artifacts-only"|"full",
* "gstack_brain_git": true|false,
* "gstack_artifacts_remote": "https://..." | "",
* "gbrain_local_status": "ok"|"no-cli"|"missing-config"|"broken-config"|"broken-db"
* }
*
* Backward compatibility (per plan codex #5): the 9 pre-existing fields stay
* identical in name + type + value semantics. One new field added:
* gbrain_local_status. Key order may differ from the bash version's `jq -n`
* output — downstream parsers must not depend on key order (none currently do).
*
* Env:
* GSTACK_HOME — override ~/.gstack for state lookups (used by tests).
* HOME — effective user home (drives ~/.gbrain/config.json path).
* GSTACK_DETECT_NO_CACHE=1 — bypass the 60s local-status cache.

# Why gstack uses Diataxis for documentation
The two doc skills in gstack — `/document-release` and `/document-generate` — both speak Diataxis. New entities get scored across four quadrants. Coverage gaps surface in PR bodies tagged by quadrant. This doc explains why that vocabulary is load-bearing, and why a simpler "just write markdown" approach falls down at the scale gstack operates at.
## The problem
Documentation rot is the easiest kind of rot to ignore. Code stops compiling and you notice immediately. A test fails and CI screams. Docs go stale silently — the README still parses, the install command still copy-pastes — and the only signal is a confused user weeks later filing an issue or quietly walking away.
gstack has more than 45 skills. Every one is a SKILL.md plus a `.tmpl` template plus, ideally, a getting-started tutorial somewhere and an explanation of why it works the way it does. Multiply that by however many gstack users have similar surface-area in their own projects and the maintenance load is real.
The naive failure mode is "every team writes docs in their own format." One project has a Wiki. Another has nested README files. A third has reference-only API docs and no tutorials. A fourth has tutorials that no longer compile. You can't write tooling that audits across all of those because there's no shared vocabulary for what good coverage means.
The second failure mode is more subtle: even when a team is disciplined, they tend to write the kind of doc that matches their current state of mind. Engineers in build mode write reference. Engineers in launch mode write tutorials. Engineers in maintenance mode write troubleshooting how-tos. No one wakes up and says "today I'll write the explanation doc for why we chose this architecture" — so explanation rot accumulates fastest.
## The approach
Diataxis (Daniele Procida, originally at Divio, now adopted across CPython, Django, NumPy, FastAPI, GitHub docs, and many others) splits documentation into four quadrants based on **reader intent**:
```
THEORETICAL PRACTICAL
(understanding) (doing)
STUDY +-----------------------------+----------------------------+
(learning) | | |
| EXPLANATION | TUTORIAL |
| "Why does X exist?" | "Walk me through X |
| | for the first time" |
| discusses code | teaches code |
| | |
+-----------------------------+----------------------------+
WORK +-----------------------------+----------------------------+
(using) | | |
| REFERENCE | HOW-TO |
| "What is the exact | "How do I accomplish Y |
| signature of Y?" | using X?" |
| | |
| describes code | uses code |
| | |
+-----------------------------+----------------------------+
```
A reader in tutorial mode is learning by doing. They want a guided path with guaranteed success. A reader in how-to mode already knows the basics and wants the recipe for a specific task. A reader in reference mode wants accurate, complete, fact-table coverage of the API. A reader in explanation mode wants to understand a design decision.
The same person reads a project from each of these modes at different times. The same paragraph cannot serve all four — tutorials need handholding that would slow down a reference reader; reference needs completeness that would overwhelm a tutorial reader.
## Why this matters as a coverage lens
A coverage map written in Diataxis terms gives you a deterministic answer to "did docs get updated?" — not "is there a README" but "is there a tutorial for this new skill, a how-to for the common task, a reference for the API, and an explanation for the non-obvious design choice?"
`/document-release` Step 1.5 walks the diff, extracts new public surface (skills, CLI flags, config options, API endpoints), and scores each entity across the four quadrants. Items with zero coverage become **critical gaps**. Items with only reference coverage (the most common failure mode in gstack's own history) become **common gaps**. Both land in the PR body where reviewers see them.
`/document-generate` writes docs in the four quadrants intentionally. It refuses to mix them: a tutorial does not get a "Configuration" section, a reference doc does not get a "What you'll build" paragraph. The skill's 9 steps go reference → explanation → how-to → tutorial because that ordering matches the dependency: reference fixes the vocabulary, explanation justifies the design, how-tos build on both, tutorials are the last and hardest.
## Trade-offs
**Diataxis adds vocabulary that readers must learn.** A user who's never heard of "reference vs explanation" might find the labels strange at first. The mitigation is that Diataxis labels are self-explanatory once you've seen them once, and the labels never appear in the docs themselves — they appear in the coverage map and PR body, where reviewers see them, not end users.
**Four files instead of one.** A small skill might have one `docs/SKILL.md` file that mixes all four modes. Diataxis splits that into four. The mitigation: AI generation makes the four-file structure cheap, the cross-linking between quadrants is mechanical (every reference doc links to its how-to, every how-to links to its reference, etc.), and the gains in audit-ability are substantial — `/document-release` can score coverage automatically.
**Diataxis is not the only good framework.** "Every page is page one" (Mark Baker), the four kinds of docs in the *Write the Docs* community, the Google developer documentation style guide — all have different cuts. gstack picked Diataxis because it has the strongest external adoption (CPython, Django, NumPy, FastAPI, etc.), which means downstream users have the highest chance of having seen the vocabulary before, and the quadrant labels translate cleanly to coverage-map signals.
## Alternatives considered
**"Just write README sections."** Tried implicitly across gstack's history. Failure mode: tutorials accumulated in README until READMEs were 800+ lines and nobody read them past line 50. Diataxis splits them into dedicated files, each discoverable from README's table of contents.
**Custom in-house taxonomy.** Tempting because it could be tailored. Rejected because every team would invent their own vocabulary and `/document-release` would lose its cross-project audit power. Diataxis is the lingua franca.
**Auto-generated reference only.** Tried via tools like JSDoc / TypeDoc / Sphinx for many projects. Reference docs without explanation become impenetrable for newcomers; without tutorials, the API is hard to onboard onto. Reference is necessary but not sufficient.
**No documentation framework at all, just gut-check.** The status quo for most projects. Fails silently — users walk away rather than file issues, so the feedback loop is broken. Diataxis gives a structured signal even before users complain.

# How to document a feature you just shipped
This is the post-ship workflow: you merged a PR, the docs are stale, and you want a coverage map plus filled gaps in one pass. You'll run `/document-release` to audit, then `/document-generate` to fill the gaps it finds.
## Prerequisites
- gstack installed (`./setup` complete; verify with `which gstack` or by typing `/` in Claude Code and seeing skills listed)
- The branch with your shipped feature is checked out
- A PR exists on GitHub or GitLab (recommended — the workflow updates the PR body with a coverage map)
If no PR exists yet, run `/ship` first to create one; that's what `/document-release` is designed to run against.
## Steps
### 1. Audit current coverage
Run:
```
/document-release
```
The skill walks your diff against the base branch, extracts new public surface (skills, CLI flags, config options, API endpoints, new modules), and scores each entity across the four Diataxis quadrants. You'll see a coverage map like:
```
Coverage map:
[entity] [reference?] [how-to?] [tutorial?] [explanation?]
/new-skill ✅ AGENTS.md ❌ ❌ ❌
--new-flag ✅ README ✅ README ❌ ❌
FooProcessor ❌ ❌ ❌ ❌
```
Items with zero coverage are **critical gaps**. Items with only reference coverage are **common gaps**. Both land in the PR body as a `### Documentation Debt` subsection so reviewers see them.
If `/document-release` reports everything is covered, you're done. Skip the rest of this how-to.
### 2. Read the documentation debt section in the PR body
Open your PR (the skill prints the URL). Scroll to `## Documentation``### Documentation Debt`. Each item is tagged with the Diataxis quadrant that would fill it:
```
### Documentation Debt
- ⚠️ /new-skill — has reference in AGENTS.md but no how-to example in README. Diataxis quadrant: how-to.
- ⚠️ FooProcessor — zero coverage. Diataxis quadrants: reference, explanation.
```
This is the input to the next step. Each line tells you what's missing and which quadrant fills it.
### 3. Fill the gaps with /document-generate
Run:
```
/document-generate
```
When the skill asks about scope, tell it the specific entities flagged in the debt section. The skill reads the codebase (its Step 1 archaeology phase is mandatory), partitions by Diataxis quadrant, and writes the missing docs.
You can also let the skill auto-discover: if /document-release passed you the gaps explicitly (it does this when chained), `/document-generate` already knows what to write.
### 4. Verify the gaps closed
Re-run `/document-release`:
```
/document-release
```
The coverage map should now show the previously-flagged entities with green checkmarks in the previously-empty quadrants. The PR body's Documentation Debt section should be empty or reduced to items you intentionally deferred.
## Verification
Open your PR and confirm:
1. The PR body has a `## Documentation` section with a doc-diff preview.
2. The `### Documentation Debt` subsection lists zero critical gaps (or only items you knowingly deferred).
3. Each generated doc file in `docs/` opens cleanly and cross-links to siblings (reference → how-to → tutorial → explanation).
4. Run `grep -rE '\]\([^)]*\.md\)' docs/` and verify no link points to a missing file.
If all four check, your PR is ready to land with complete documentation.
## Troubleshooting
**`/document-release` reports "No public surface changes detected."**
The diff is internal-only (refactors, tests, infra). No docs are needed. Skip to landing.
**The Diataxis quadrant tag on a gap doesn't match what you'd expect.**
The skill uses an entity taxonomy to decide which quadrants matter (CLI flags want reference + how-to; internal modules want reference + explanation; user-facing features want all four). If you disagree, you can override by hand-editing the docs after generation. The audit is a guide, not a constraint.
**`/document-generate` writes a tutorial that takes 8 steps to reach a working result.**
Tutorials should hit a working result in 3 steps or fewer. Re-run the skill and ask it to compress, or hand-edit. The Step 8 Quality Self-Review catches some of these but not all.
**You want to document a feature but no PR exists yet.**
Run `/ship` first to create the PR, then this workflow. Without a PR, `/document-release` can still audit but skips the PR-body update.
**A generated reference doc has hallucinated API signatures.**
File a bug. The skill's Step 1 archaeology is supposed to read implementation files end-to-end, not just signatures, specifically to prevent this. Include the generated text and the actual code so we can trace why the archaeology missed it.

# Tutorial: generate docs for a feature in 90 seconds
You'll run `/document-generate` against a project you already have, watch it write tutorial / how-to / reference / explanation docs in the right places, and end with a coverage map you can drop into a PR. By the end, you'll know the four moves: scope, archaeology, partition, write.
## What you'll need
- gstack installed (`git clone --single-branch --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup`)
- Claude Code running in any project that has at least one piece of public surface (a CLI command, an exported function, a config option, a skill, an API endpoint)
- About 90 seconds
You do not need a `docs/` directory in advance — the skill creates one if it's missing. You do not need to know Diataxis terminology — the skill labels the output for you.
## Step 1: Invoke the skill in any project
Open Claude Code in the project you want to document. Type:
```
/document-generate
```
You'll see the skill ask one question about output target:
```
A) Write documentation inline in existing files (README, ARCHITECTURE, etc.)
B) Create standalone documentation files (e.g., docs/ directory)
C) Both — inline summaries in existing files + deep docs in standalone files
RECOMMENDATION: Choose C because it maximizes both discoverability and depth.
```
Pick C. You'll get a README pointer plus a full set of standalone docs.
## Step 2: Watch the archaeology run
The skill goes silent for ~30 seconds while it reads the codebase. This is intentional — the Step 1 "Codebase Archaeology" phase is the most important step in the workflow. The skill is reading:
- The full repository structure
- README, ARCHITECTURE, CONTRIBUTING, CLAUDE.md (the entry points)
- The implementation files for whatever you're documenting (full file, not just signatures)
- The tests (which reveal edge cases and intended behavior)
- Inline comments tagged `// NOTE:`, `// DESIGN:`, `// WHY:`
When it finishes, you'll see a line like:
```
Researched 47 files, identified 12 public surface items, 8 concepts, and 4 design decisions.
```
That number tells you the skill actually read the code rather than guessing from filenames.
## Step 3: See the Diataxis partition plan
The skill prints a partition plan showing which quadrants it'll write for which entity:
```
Documentation plan:
[entity] [tutorial] [how-to] [reference] [explanation]
WidgetService ✅ new ✅ new ✅ new ✅ new
--verbose flag ❌ ✅ new ✅ inline ❌
Bayesian scheduler ❌ ❌ ✅ new ✅ new
```
Not every entity needs all four quadrants. CLI flags get reference + how-to. Internal modules get reference + explanation. User-facing features get all four. The skill picks based on entity type.
If the plan has more than 5 documents, the skill asks you to confirm before proceeding. Otherwise it goes.
## Step 4: Read the first doc that lands
Reference docs land first because they fix the vocabulary. You'll see lines like:
```
GENERATED: docs/reference-widget-service.md
```
Open that file. It has a strict structure: one-paragraph intro, complete API listing with types and defaults, 2-3 runnable examples, and a Related section linking to the how-to and tutorial that will land next.
This is what reference docs look like in Diataxis: factual, exhaustive, no narrative. If you find yourself wanting to explain *why* an option exists, that belongs in the explanation doc the skill will write next.
## Step 5: See the explanation, how-to, and tutorial appear
In quick succession (each ~5-10 seconds), the skill writes the remaining quadrants:
```
GENERATED: docs/explanation-widget-architecture.md
GENERATED: docs/howto-create-a-custom-widget.md
GENERATED: docs/tutorial-build-your-first-widget.md
```
Open each one. Notice they don't repeat each other:
- **Explanation** leads with the problem, then the approach, then trade-offs and alternatives considered
- **How-to** has prerequisites, numbered steps with exact commands, a verification section, and a troubleshooting section
- **Tutorial** gets you to a working result in under 3 steps, ends with "What you built"
The skill enforces these structures. If a how-to was missing a verification section, the Step 8 Quality Self-Review caught it before commit.
## Step 6: Check cross-linking
Every doc links to the others. Reference doc Related section: links to how-to and tutorial. How-to Related section: links to reference. Tutorial "What you built" section: links to reference for deeper exploration.
Run a grep to verify no broken links:
```bash
grep -rE '\]\([^)]*\.md\)' docs/ | head -10
```
Every linked file should exist. The skill's Step 7 "Cross-Document Linking & Discoverability" checks this before commit.
## Step 7: See the coverage summary in the PR body
If you're on a feature branch with an open PR, the skill updates the PR body with a `## Documentation Generated` table:
```
## Documentation Generated
| File | Quadrant | Description |
|------|----------|-------------|
| docs/tutorial-build-your-first-widget.md | Tutorial | Walk-through from install to first working widget |
| docs/reference-widget-service.md | Reference | Complete widget API with types, defaults, examples |
| docs/explanation-widget-architecture.md | Explanation | Why widgets are isolated services |
| docs/howto-create-a-custom-widget.md | How-to | Creating and registering custom widgets |
```
A reviewer opening the PR sees the table and knows immediately what kind of coverage shipped.
## What you built
You now have four documents that serve four different readers:
- A newcomer to your project can read `tutorial-*.md` and get something working
- An experienced user can read `howto-*.md` to accomplish a specific task
- An API caller can read `reference-*.md` for exact signatures
- A code reviewer can read `explanation-*.md` to understand the design
Each one is short enough to maintain. Each one has a single job. The PR body shows which quadrants were covered. If you run `/document-release` later, the Diataxis coverage map will report this entity as fully covered (4/4 quadrants).
## What to do next
- **If you have gaps** /document-release flagged but didn't fill: run `/document-generate` again, scoped to those entities specifically.
- **If you want to understand why the four quadrants exist:** read [explanation-diataxis-in-gstack.md](./explanation-diataxis-in-gstack.md).
- **If you want to document one specific shipped feature** (not the whole project): read [howto-document-a-shipped-feature.md](./howto-document-a-shipped-feature.md).
- **Reference for the skill itself:** [`document-generate/SKILL.md`](../document-generate/SKILL.md).

{{PREAMBLE}}
{{BASE_BRANCH_DETECT}}
# Document Generate: Diataxis Documentation Writer
You are running the `/document-generate` workflow. Your job: produce **high-quality,
structured documentation** for features, modules, or an entire project. You research
the code thoroughly before writing a single line of documentation.
This skill can be invoked two ways:
1. **Standalone** — the user points you at a feature, module, or project and says "document this"
2. **From /document-release** — the coverage map identified gaps; you fill them
You follow the **Diataxis framework** — four quadrants of documentation, each serving a
different reader need:
- **Tutorial** — learning-oriented, walks a newcomer through a working example step-by-step
- **How-to** — task-oriented, shows how to accomplish a specific goal (assumes basic familiarity)
- **Reference** — information-oriented, complete and accurate technical description
- **Explanation** — understanding-oriented, explains why things work the way they do
**Philosophy: research the whole, then write the parts.** Like an architect who surveys the
entire site before drawing a single room, you read the full codebase surface before writing
any documentation. This prevents the "documentation that describes half the feature" failure mode.
---
## Step 0: Scope & Intent
1. Determine what to document:
- **If invoked with a specific target** (feature, module, file, skill): scope is that target
- **If invoked for an entire project**: scope is the full project
- **If called from /document-release with gaps**: scope is the specific entities from the coverage map
2. Use AskUserQuestion to confirm scope and ask about documentation target:
- A) Write documentation inline in existing files (README, ARCHITECTURE, etc.)
- B) Create standalone documentation files (e.g., `docs/` directory)
- C) Both — inline summaries in existing files + deep docs in standalone files
RECOMMENDATION: Choose C because it maximizes both discoverability and depth.
3. Determine the output format:
- If the project already has a `docs/` directory, follow its conventions
- If the project uses a doc framework (Nextra, Docusaurus, MkDocs, VitePress), follow its format
- Otherwise, use plain Markdown files in `docs/`
---
## Step 1: Codebase Archaeology (Research Phase)
**This is the most important step.** Do not skip or rush it. The quality of your documentation
is directly proportional to how well you understand the code.
1. **Map the project structure:**
```bash
find . -type f -not -path "./.git/*" -not -path "./node_modules/*" -not -path "./.gstack/*" -not -path "./dist/*" -not -path "./build/*" -not -path "./.next/*" | head -200
```
2. **Read the entry points.** Identify and read:
- README.md, ARCHITECTURE.md, CONTRIBUTING.md, CLAUDE.md / AGENTS.md
- package.json / Cargo.toml / pyproject.toml / go.mod (understand the project type)
- Main entry files (index.ts, main.rs, app.py, cmd/main.go)
- Configuration files and examples
3. **Read the source code for each target entity.** For each feature/module you're documenting:
- Read the implementation files end-to-end (not just signatures)
- Read the tests — they reveal intended behavior, edge cases, and usage patterns
- Read related modules that the target depends on or is depended upon by
- Read any existing inline comments, especially `// NOTE:`, `// DESIGN:`, `// WHY:`
4. **Build a concept map.** Before writing, produce an internal outline:
```
Target: [feature/module name]
Purpose: [one sentence — what problem does it solve?]
Key concepts: [list the 3-5 concepts a reader must understand]
Public surface: [commands, functions, config options, API endpoints]
Dependencies: [what it needs from other modules]
Dependents: [what relies on it]
Edge cases: [from reading tests and code]
Design decisions: [any non-obvious "why" choices]
```
5. Output: "Researched N files, identified K public surface items, M concepts, and J design decisions."
---
## Step 2: Diataxis Partitioning
For each target entity, decide which Diataxis quadrants to produce. Not every entity needs all four.
**Decision matrix:**
| Entity type | Tutorial? | How-to? | Reference? | Explanation? |
|---|---|---|---|---|
| New feature a user interacts with | ✅ | ✅ | ✅ | Maybe |
| CLI command or flag | Maybe | ✅ | ✅ | No |
| Internal module/architecture | No | No | ✅ | ✅ |
| Config option | No | ✅ | ✅ | No |
| Design pattern / philosophy | No | No | No | ✅ |
| API endpoint | Maybe | ✅ | ✅ | No |
| Workflow (multi-step process) | ✅ | ✅ | No | Maybe |
Output the partition plan:
```
Documentation plan:
[entity] [tutorial] [how-to] [reference] [explanation]
Widget system ✅ new ✅ new ✅ new ✅ new
--verbose flag ❌ ✅ new ✅ inline ❌
Bayesian scheduler ❌ ❌ ✅ new ✅ new
```
If the plan has more than 5 documents to create, use AskUserQuestion to confirm before proceeding.
For smaller scopes, proceed directly.
---
## Step 3: Write Reference Documentation First
Reference docs are the foundation. They are factual, complete, and derived directly from code.
Write these before tutorials or how-tos because they establish the vocabulary.
**Reference doc template:**
```markdown
# [Entity Name]
[One paragraph: what it is, what it does, when you'd use it.]
## API / Interface
[Complete listing of public surface: functions, commands, config options, parameters.
Include types, defaults, and constraints. Pull directly from code — do not paraphrase
loosely.]
## Options / Configuration
[If applicable: every option with its type, default, and effect.]
## Examples
[2-3 concrete examples showing actual usage. Prefer real command output or code that
would actually compile/run.]
## Related
[Links to other reference docs, how-tos, or explanations that provide context.]
```
**Rules for reference docs:**
- Accuracy over elegance. Every claim must be traceable to code.
- Include types, defaults, and constraints. "Accepts a string" is insufficient — "Accepts a
string (max 256 chars, must match `^[a-z-]+$`)" is reference-grade.
- Show real examples that would actually work if copy-pasted.
- Do not explain *why* — that belongs in explanation docs.
---
## Step 4: Write Explanation Documentation
Explanation docs answer "why does this work this way?" They are the design rationale.
**Explanation doc template:**
```markdown
# [Concept / Design Decision]
[Opening paragraph: the problem this design solves, stated in terms a smart reader
who hasn't seen the code would understand.]
## The problem
[Concrete description of what goes wrong without this design. Real failure modes,
not abstract risks.]
## The approach
[How the design solves the problem. Include diagrams (ASCII or Mermaid) for
architectural concepts.]
## Trade-offs
[What was given up. Every design decision trades something — name it explicitly.]
## Alternatives considered
[If discoverable from code comments, ADRs, or git history: what was tried or
rejected and why.]
```
**Rules for explanation docs:**
- Lead with the problem, not the solution.
- Use ASCII diagrams for architecture. They're grep-able, diff-friendly, and render everywhere.
- Name trade-offs explicitly. "We chose X over Y because Z" is the gold standard.
- Do not repeat reference material — link to it.
---
## Step 5: Write How-To Guides
How-tos are task-oriented. They assume the reader knows the basics and wants to accomplish
something specific.
**How-to doc template:**
```markdown
# How to [accomplish specific task]
[One sentence: what you'll accomplish and the end result.]
## Prerequisites
[What the reader needs before starting. Be specific — versions, installed tools,
config state.]
## Steps
1. [Action verb] [specific instruction]
```bash
[exact command]
```
[Expected output or result, if non-obvious.]
2. [Next step...]
## Verification
[How to confirm it worked. A command, a URL to visit, a test to run.]
## Troubleshooting
[Common failure modes and their fixes. Pull from tests and error handling code.]
```
**Rules for how-to docs:**
- Title starts with "How to" — no exceptions. This is the reader's entry point.
- Every step must be actionable. No "consider whether..." — instead "Run X" or "Add Y to Z".
- Include verification. The reader should never wonder "did it work?"
- Troubleshooting section is mandatory if the task can fail.
---
## Step 6: Write Tutorials
Tutorials are learning-oriented. They take a newcomer from zero to a working example.
These are the hardest to write well and the most valuable.
**Tutorial doc template:**
```markdown
# [Tutorial title — describes what you'll build/learn]
[Opening paragraph: what you'll build, why it's useful, and what you'll understand
by the end. Keep it concrete — "You'll build a working X that does Y" not
"This tutorial covers X".]
## What you'll need
[Prerequisites: tools, versions, prior knowledge. Link to installation guides.]
## Step 1: [Set up the foundation]
[Start from a clean state. Show every command. Explain what each does on first
encounter — but briefly, not a lecture.]
```bash
[exact command]
```
[Brief explanation of what just happened.]
## Step 2: [Build the first working piece]
[Get to a working, visible result as fast as possible. The reader should see
something happen within the first 3 steps.]
...
## Step N: [Final step]
## What you built
[Recap: what the reader now has and what it can do. Link to reference docs
for deeper exploration. Suggest next steps.]
```
**Rules for tutorials:**
- **Time to first result < 3 steps.** If the reader hasn't seen something work by step 3,
the tutorial is too slow.
- Every step must produce a visible change or output. No "now configure X" without showing
what changes.
- Use the exact commands the reader will type. No "run the appropriate command" abstractions.
- Error paths: if a step commonly fails, show the error and the fix inline.
- End with "What you built" — connect the tutorial back to the real use case.
---
## Step 7: Cross-Document Linking & Discoverability
After writing all documents:
1. **Add cross-links between quadrants.** Every reference doc should link to its how-to.
Every how-to should link to its reference. Tutorials should link to both.
2. **Update entry-point files.** Add references to new docs in:
- README.md — add to documentation section or table of contents
- CLAUDE.md / AGENTS.md — add to project structure if relevant
- Any existing docs index or sidebar config
3. **Verify discoverability.** Every new document must be reachable within 2 clicks from
README.md. If a docs framework is in use, add to the sidebar/nav config.
4. **Check for broken links.** Grep for any `](` references that point to files that don't exist.
---
## Step 8: Quality Self-Review
Before committing, review each document against these criteria:
**Accuracy gate:**
- [ ] Every code example compiles / runs / passes if copy-pasted
- [ ] Every API description matches the actual code signature
- [ ] Every command shown produces the output described
- [ ] No stale references to renamed/removed entities
**Completeness gate:**
- [ ] Reference docs cover 100% of public surface
- [ ] How-tos cover the top 3 tasks a user would attempt
- [ ] Tutorials get to a working result in ≤3 steps
- [ ] Explanation docs name trade-offs, not just choices
**Voice gate:**
- [ ] Written for a smart person who hasn't seen the code
- [ ] No jargon without brief inline gloss on first use
- [ ] Active voice, concrete nouns, short sentences
- [ ] "You can now..." not "The system provides..."
Fix any failures before proceeding.
---
## Step 9: Commit & Output
1. Stage new documentation files by name (never `git add -A` or `git add .`).
2. Create a commit:
```bash
git commit -m "$(cat <<'EOF'
docs: generate [scope] documentation (Diataxis)
[One-line summary of what was documented]
Quadrants: [list which quadrants were produced]
{{CO_AUTHOR_TRAILER}}
EOF
)"
```
3. Push to the current branch:
```bash
git push
```
4. **If a PR exists**, update the PR body with a `## Documentation Generated` section listing
every new file with its Diataxis quadrant and a one-line description:
```
## Documentation Generated
| File | Quadrant | Description |
|------|----------|-------------|
| docs/tutorial-getting-started.md | Tutorial | Walk-through from install to first working example |
| docs/reference-widget-api.md | Reference | Complete widget API with types, defaults, examples |
| docs/explanation-bayesian-scheduler.md | Explanation | Why the scheduler uses Bayesian inference |
| docs/howto-custom-widgets.md | How-to | Creating and registering custom widgets |
```
5. Output a structured summary:
```
Documentation generated:
Scope: [what was documented]
Files: [N] new, [M] updated
Coverage:
Tutorials: [count] ([list])
How-tos: [count] ([list])
Reference: [count] ([list])
Explanation: [count] ([list])
Quality: [pass/fail on each gate]
```
---
## Important Rules
- **Research before writing.** Step 1 is not optional. Read the code, read the tests, read the
existing docs. Insufficient research produces surface-level documentation.
- **Accuracy is non-negotiable.** Every code example must work. Every API description must match
the actual code. If you're unsure about a detail, read the source again — do not guess.
- **Diataxis quadrants serve different readers.** Do not mix tutorial content into reference docs
or reference content into how-tos. Each quadrant has a specific reader in a specific mode.
- **Time to first result in tutorials.** If a reader can't see something working by step 3,
restructure the tutorial.
- **Cross-link everything.** Isolated docs are undiscoverable docs.
- **Voice: friendly, concrete, user-forward.** Write like you're explaining to a smart person
who hasn't seen the code. Never corporate, never academic.
- **Completeness over minimalism.** AI makes comprehensive documentation cheap. Don't write
"minimal viable docs" — write complete docs. Boil the lake.

## Step 1.5: Coverage Map (Blast-Radius Analysis)
Before touching any documentation file, build a **coverage map** of what shipped vs what's
documented. This is inspired by the Diataxis framework (tutorial / how-to / reference / explanation)
— but applied as an audit lens, not a generation tool.
1. **Extract public surface changes from the diff.** Scan `git diff <base>...HEAD` for:
- New exported functions, classes, commands, CLI flags, config options, API endpoints
- New skills, workflows, or user-facing capabilities
- Renamed or removed public surface (modules, commands, features)
- New environment variables, feature flags, or configuration knobs
2. **For each new/changed public surface item, assess documentation coverage:**
```
Coverage map:
[entity] [reference?] [how-to?] [tutorial?] [explanation?]
/new-skill ✅ AGENTS.md ❌ ❌ ❌
--new-flag ✅ README ✅ README ❌ ❌
FooProcessor ❌ ❌ ❌ ❌
```
Use these definitions:
- **Reference** — factual description of what it is, its API, its options (README tables, AGENTS.md skill lists, API docs)
- **How-to** — task-oriented: "how to do X with this" (README examples, CONTRIBUTING workflows)
- **Tutorial** — learning-oriented: step-by-step walkthrough for newcomers (getting started guides)
- **Explanation** — understanding-oriented: "why this works this way" (ARCHITECTURE decisions, design rationale)
3. **Output the coverage map.** Items with zero coverage are **critical gaps** — flag them for
Step 3. Items with reference-only coverage are **common gaps** — note them for the PR body.
4. **Architecture diagram drift detection.** If ARCHITECTURE.md (or any doc) contains ASCII
diagrams or Mermaid blocks, extract entity names (modules, services, data flows) from the
diagrams. Cross-reference against the diff. Flag any diagram entities that were renamed,
split, removed, or moved in the code.
The coverage map feeds into Steps 2-3 (what to audit and fix) and Step 9 (documentation debt
summary in the PR body). Do NOT auto-generate missing documentation pages — flag gaps only.
When significant gaps are found, suggest running `/document-generate` to fill them.

## Step 1.5: Coverage Map (Blast-Radius Analysis)
Before touching any documentation file, build a **coverage map** of what shipped vs what's
documented. This is inspired by the Diataxis framework (tutorial / how-to / reference / explanation)
— but applied as an audit lens, not a generation tool.
1. **Extract public surface changes from the diff.** Scan `git diff <base>...HEAD` for:
- New exported functions, classes, commands, CLI flags, config options, API endpoints
- New skills, workflows, or user-facing capabilities
- Renamed or removed public surface (modules, commands, features)
- New environment variables, feature flags, or configuration knobs
2. **For each new/changed public surface item, assess documentation coverage:**
```
Coverage map:
[entity] [reference?] [how-to?] [tutorial?] [explanation?]
/new-skill ✅ AGENTS.md ❌ ❌ ❌
--new-flag ✅ README ✅ README ❌ ❌
FooProcessor ❌ ❌ ❌ ❌
```
Use these definitions:
- **Reference** — factual description of what it is, its API, its options (README tables, AGENTS.md skill lists, API docs)
- **How-to** — task-oriented: "how to do X with this" (README examples, CONTRIBUTING workflows)
- **Tutorial** — learning-oriented: step-by-step walkthrough for newcomers (getting started guides)
- **Explanation** — understanding-oriented: "why this works this way" (ARCHITECTURE decisions, design rationale)
3. **Output the coverage map.** Items with zero coverage are **critical gaps** — flag them for
Step 3. Items with reference-only coverage are **common gaps** — note them for the PR body.
4. **Architecture diagram drift detection.** If ARCHITECTURE.md (or any doc) contains ASCII
diagrams or Mermaid blocks, extract entity names (modules, services, data flows) from the
diagrams. Cross-reference against the diff. Flag any diagram entities that were renamed,
split, removed, or moved in the code.
The coverage map feeds into Steps 2-3 (what to audit and fix) and Step 9 (documentation debt
summary in the PR body). Do NOT auto-generate missing documentation pages — flag gaps only.
When significant gaps are found, suggest running `/document-generate` to fill them.

## Step 1.5: Broken-local-engine remediation (plan D4)
Read `gbrain_local_status` from the Step 1 detect output. **If it's `broken-db`
or `broken-config` AND no shortcut flag was passed**, the user has a
non-working local engine (Garry's repro: `~/.gbrain/config.json` points at a
dead Postgres URL). Fire a targeted AskUserQuestion BEFORE Step 2:
> D# — Your local gbrain engine isn't responding. How do you want to fix it?
> Project/branch/task: <one-sentence grounding using detected slug + branch>
> ELI10: gbrain has a config at `~/.gbrain/config.json` but the engine it points
> at isn't reachable. That could be a transient outage (Postgres container
> stopped, Tailscale down) OR a stale config you want to abandon. Different
> remediation for each case.
> Stakes if we pick wrong: "Switch to PGLite" overwrites your existing config
> (one-way door if the user actually wanted the broken engine). "Retry" preserves
> existing state for transient cases.
> Recommendation: A (Retry) — always try the cheap option first; if engine is
> just temporarily down it'll come back without any destructive change.
> Note: options differ in kind, not coverage — no completeness score.
> A) Retry — re-probe the engine (recommended; ~80ms)
> ✅ Cheapest test: re-runs `gbrain sources list` to see if engine is back
> ✅ Zero side effects; existing config preserved
> ❌ If engine is permanently dead, retries forever; user must choose another option
> B) Switch to local PGLite (one-way — moves existing config to .bak)

/**
* Tests the .bak-rollback contract used by /setup-gbrain Step 1.5 (broken-db
* repair) and Step 4.5 (Path 4 opt-in to local PGLite), per plan D7.
*
* These code paths live in the skill TEMPLATE, not in a TypeScript helper
* the skill follows AI-readable instructions. The instructions specify the
* exact sequence:
*
* 1. mv ~/.gbrain/config.json ~/.gbrain/config.json.gstack-bak-$(date +%s)
* 2. gbrain init --pglite --json
* 3. on non-zero exit: mv .bak back; surface error
*
* This test extracts that sequence as a shell function and verifies the
* rollback contract using a fake `gbrain` binary that fails on init. It's
* the test that proves "what the skill template says, when followed
* mechanically, actually preserves the user's broken config on failure."
*
* Per plan codex #10 / explicit rollback scope: we only promise to restore
* the config.json file. The PGLite directory at ~/.gbrain/pglite/ may end
* up in a partial state that's documented to the user, not auto-cleaned.
