Garry Tan 9dbaf906cf feat(v1.9.0.0): gbrain-sync — cross-machine gstack memory (#1151)
* feat(gbrain-sync): queue primitives + writer shims

Adds bin/gstack-brain-enqueue (atomic append to sync queue) and
bin/gstack-jsonl-merge (git merge driver, ts-sort with SHA-256 fallback).
Wires one backgrounded enqueue call into learnings-log, timeline-log,
review-log, and developer-profile --migrate. question-log and
question-preferences stay local per Codex v2 decision.

gstack-config gains gbrain_sync_mode (off/artifacts-only/full) and
gbrain_sync_mode_prompted keys, plus GSTACK_HOME env alignment so
tests don't leak into real ~/.gstack/config.yaml.

* feat(gbrain-sync): --once drain + secret scan + push

bin/gstack-brain-sync is the core sync binary. Subcommands: --once
(drain queue, allowlist-filter, privacy-class-filter, secret-scan
staged diff, commit with template, push with fetch+merge retry),
--status, --skip-file <path>, --drop-queue --yes, --discover-new
(cursor-based detection of artifact writes that skip the shim).

Secret regex families: AWS keys, GitHub tokens (ghp_/gho_/ghu_/ghs_/
ghr_/github_pat_), OpenAI sk-, PEM blocks, JWTs, bearer-token-in-JSON.
On hit: unstage, preserve queue, print remediation hint (--skip-file
or edit), exit clean. No daemon — invoked by preamble at skill
boundaries.

* feat(gbrain-sync): init, restore, uninstall, consumer registry

bin/gstack-brain-init: idempotent first-run. git init ~/.gstack/,
.gitignore=*, canonical .brain-allowlist + .brain-privacy-map.json,
pre-commit secret-scan hook (defense-in-depth), merge driver registration
via git config, gh repo create --private OR arbitrary --remote <url>,
initial push, ~/.gstack-brain-remote.txt for new-machine discovery,
GBrain consumer registration via HTTP POST.

bin/gstack-brain-restore: safe new-machine bootstrap. Refuses clobber
of existing allowlisted files, clones to staging, rsync-copies tracked
files, re-registers merge drivers (required — not cloned from remote),
rehydrates consumers.json, prompts for per-consumer tokens.

bin/gstack-brain-uninstall: clean off-ramp. Removes .git + .brain-*
files + consumers.json + config keys. Preserves user data (learnings,
plans, retros, profile). Optional --delete-remote for GitHub repos.

bin/gstack-brain-consumer + bin/gstack-brain-reader (symlink alias):
registry management. Internal 'consumer' term; user-facing 'reader'
per DX review decision.

* feat(gbrain-sync): preamble block — privacy gate + boundary sync

scripts/resolvers/preamble/generate-brain-sync-block.ts emits bash that
runs at every skill invocation:
- Detects ~/.gstack-brain-remote.txt on machines without local .git
  and surfaces a restore-available hint (does NOT auto-run restore).
- Runs gstack-brain-sync --once at skill start to drain any pending
  writes (and at skill end via prose instruction).
- Once-per-day auto-pull (cached via .brain-last-pull) for append-only
  JSONL files.
- Emits BRAIN_SYNC: status line every skill run.

Also emits prose for the host LLM to fire the one-time privacy
stop-gate (full / artifacts-only / off) when gbrain is detected and
gbrain_sync_mode_prompted is false. Wired into preamble.ts composition.

* test(gbrain-sync): 27-test consolidated suite

test/brain-sync.test.ts covers:
- Config: validation, defaults, GSTACK_HOME env isolation
- Enqueue: no-op gates, skip list, concurrent atomicity, JSON escape
- JSONL merge driver: 3-way + ts-sort + SHA-256 fallback
- Init + sync: canonical file creation, merge driver registration,
  push-reject + fetch+merge retry path
- Init refuses different remote (idempotency)
- Cross-machine restore round-trip (machine A write → machine B sees)
- Secret scan across all 6 regex families (AWS, GH, OpenAI, PEM, JWT,
  bearer-JSON). --skip-file unblock remediation
- Uninstall removes sync config, preserves user data
- --discover-new idempotence via mtime+size cursor

Behaviors verified via integration smokes during implementation. Known
follow-up: bun-test 5s default timeout needs 30s wrapper for
spawnSync-heavy tests.

* docs(gbrain-sync): user guide + error lookup + README section

docs/gbrain-sync.md: setup walkthrough, privacy modes, cross-machine
workflow, secret protection, two-machine conflict handling, uninstall,
troubleshooting reference.

docs/gbrain-sync-errors.md: problem/cause/fix index for every
user-visible error. Patterned on Rust's error docs + Stripe's API
error reference.

README.md: 'Cross-machine memory with GBrain sync' section near the
top (discovery moment), plus docs-table entry.

* chore: bump version and changelog (v1.7.0.0)

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* chore: regenerate SKILL.md files for gbrain-sync preamble block

Re-runs bun run gen:skill-docs after adding generateBrainSyncBlock
to scripts/resolvers/preamble.ts in a2aa8a07. CI check-freshness
caught the drift. All 36 SKILL.md files regenerated with the new
skill-start bash block + privacy-gate prose + skill-end sync
instructions baked in.

* fix(test): session-awareness reads AskUserQuestion Format from a Tier 2+ SKILL.md

The test was reading ROOT/SKILL.md (browse skill, Tier 1) which never
contained '## AskUserQuestion Format' — that section is only emitted
for Tier 2+ skills by scripts/resolvers/preamble.ts. As a result the
agent was prompted with an empty format guide and only emitted
'RECOMMENDATION' intermittently, making the test flaky.

Pre-existing on main (same ROOT/SKILL.md shape there) — surfaced now
because the agent run didn't hit the RECOMMENDATION/recommend/option a
fallback strings in this particular attempt.

Fix: read from office-hours/SKILL.md (Tier 3, always has the section)
with a fallback that scans for the first top-level skill dir whose
SKILL.md contains the header. Future template moves won't break this
test again.

* chore: bump to v1.9.0.0 for gbrain-sync landing

Changes just the VERSION + package.json + CHANGELOG header (1.7.0.0 → 1.9.0.0
and date 2026-04-22 → 2026-04-23). No code changes. User call: land gbrain-sync
as a bigger-signal release above main's 1.6.4.0, skipping 1.8.0.0.

```
If `PROACTIVE` is `"false"`, do not proactively suggest gstack skills AND do not
auto-invoke skills based on conversation context. Only run skills the user explicitly
types (e.g., /qa, /ship). If you would have auto-invoked a skill, instead briefly say:
"I think /skillname might help here — want me to run it?" and wait for confirmation.
The user opted out of proactive behavior.
If `SKILL_PREFIX` is `"true"`, the user has namespaced skill names. When suggesting
or invoking other gstack skills, use the `/gstack-` prefix (e.g., `/gstack-qa` instead
of `/qa`, `/gstack-ship` instead of `/ship`). Disk paths are unaffected — always use
`~/.claude/skills/gstack/[skill-name]/SKILL.md` for reading skill files.
If output shows `UPGRADE_AVAILABLE <old> <new>`: read `~/.claude/skills/gstack/gstack-upgrade/SKILL.md` and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined).
If output shows `JUST_UPGRADED <from> <to>` AND `SPAWNED_SESSION` is NOT set: tell
the user "Running gstack v{to} (just updated!)" and then check for new features to
surface. For each per-feature marker below, if the marker file is missing AND the
feature is plausibly useful for this user, use AskUserQuestion to let them try it.
Fire once per feature per user, NOT once per upgrade.
**In spawned sessions (`SPAWNED_SESSION` = "true"): SKIP feature discovery entirely.**
Just print "Running gstack v{to}" and continue. Orchestrators do not want interactive
prompts from sub-sessions.
**Feature discovery markers and prompts** (one at a time, max one per session):
1. `~/.claude/skills/gstack/.feature-prompted-continuous-checkpoint`
Prompt: "Continuous checkpoint auto-commits your work as you go with `WIP:` prefix
so you never lose progress to a crash. Local-only by default — doesn't push
anywhere unless you turn that on. Want to try it?"
Options: A) Enable continuous mode, B) Show me first (print the section from
the preamble Continuous Checkpoint Mode), C) Skip.
If A: run `~/.claude/skills/gstack/bin/gstack-config set checkpoint_mode continuous`.
Always: `touch ~/.claude/skills/gstack/.feature-prompted-continuous-checkpoint`
2. `~/.claude/skills/gstack/.feature-prompted-model-overlay`
Inform only (no prompt): "Model overlays are active. `MODEL_OVERLAY: {model}`
shown in the preamble output tells you which behavioral patch is applied.
Override with `--model` when regenerating skills (e.g., `bun run gen:skill-docs
--model gpt-5.4`). Default is claude."
Always: `touch ~/.claude/skills/gstack/.feature-prompted-model-overlay`
After handling JUST_UPGRADED (prompts done or skipped), continue with the skill
workflow.
If `WRITING_STYLE_PENDING` is `yes`: You're on the first skill run after upgrading
to gstack v1. Ask the user once about the new default writing style. Use AskUserQuestion:
> v1 prompts = simpler. Technical terms get a one-sentence gloss on first use,
> questions are framed in outcome terms, sentences are shorter.
>
> Keep the new default, or prefer the older tighter prose?
Options:
- A) Keep the new default (recommended — good writing helps everyone)
- B) Restore V0 prose — set `explain_level: terse`
If A: leave `explain_level` unset (defaults to `default`).
If B: run `~/.claude/skills/gstack/bin/gstack-config set explain_level terse`.
Always run (regardless of choice):
```bash
rm -f ~/.gstack/.writing-style-prompt-pending
touch ~/.gstack/.writing-style-prompted
```
This only happens once. If `WRITING_STYLE_PENDING` is `no`, skip this entirely.
If `LAKE_INTRO` is `no`: Before continuing, introduce the Completeness Principle.
Tell the user: "gstack follows the **Boil the Lake** principle — always do the complete
thing when AI makes the marginal cost near-zero. Read more: https://garryslist.org/posts/boil-the-ocean"
Then offer to open the essay in their default browser:
```bash
open https://garryslist.org/posts/boil-the-ocean
touch ~/.gstack/.completeness-intro-seen
```
Only run `open` if the user says yes. Always run `touch` to mark as seen. This only happens once.
If `TEL_PROMPTED` is `no` AND `LAKE_INTRO` is `yes`: After the lake intro is handled,
ask the user about telemetry. Use AskUserQuestion:
> Help gstack get better! Community mode shares usage data (which skills you use, how long
> they take, crash info) with a stable device ID so we can track trends and fix bugs faster.
> No code, file paths, or repo names are ever sent.
> Change anytime with `gstack-config set telemetry off`.
Options:
- A) Help gstack get better! (recommended)
- B) No thanks
If A: run `~/.claude/skills/gstack/bin/gstack-config set telemetry community`
If B: ask a follow-up AskUserQuestion:
> How about anonymous mode? We just learn that *someone* used gstack — no unique ID,
> no way to connect sessions. Just a counter that helps us know if anyone's out there.
Options:
- A) Sure, anonymous is fine
- B) No thanks, fully off
If B→A: run `~/.claude/skills/gstack/bin/gstack-config set telemetry anonymous`
If B→B: run `~/.claude/skills/gstack/bin/gstack-config set telemetry off`
Always run:
```bash
touch ~/.gstack/.telemetry-prompted
```
This only happens once. If `TEL_PROMPTED` is `yes`, skip this entirely.
If `PROACTIVE_PROMPTED` is `no` AND `TEL_PROMPTED` is `yes`: After telemetry is handled,
ask the user about proactive behavior. Use AskUserQuestion:
> gstack can proactively figure out when you might need a skill while you work —
> like suggesting /qa when you say "does this work?" or /investigate when you hit
> a bug. We recommend keeping this on — it speeds up every part of your workflow.
Options:
- A) Keep it on (recommended)
- B) Turn it off — I'll type /commands myself
If A: run `~/.claude/skills/gstack/bin/gstack-config set proactive true`
If B: run `~/.claude/skills/gstack/bin/gstack-config set proactive false`
Always run:
```bash
touch ~/.gstack/.proactive-prompted
```
This only happens once. If `PROACTIVE_PROMPTED` is `yes`, skip this entirely.
If `HAS_ROUTING` is `no` AND `ROUTING_DECLINED` is `false` AND `PROACTIVE_PROMPTED` is `yes`:
Check if a CLAUDE.md file exists in the project root. If it does not exist, create it.
Use AskUserQuestion:
> gstack works best when your project's CLAUDE.md includes skill routing rules.
> This tells Claude to use specialized workflows (like /ship, /investigate, /qa)
> instead of answering directly. It's a one-time addition, about 15 lines.
Options:
- A) Add routing rules to CLAUDE.md (recommended)
- B) No thanks, I'll invoke skills manually
If A: Append this section to the end of CLAUDE.md:
```markdown
## Skill routing
When the user's request matches an available skill, invoke it via the Skill tool. The
skill has multi-step workflows, checklists, and quality gates that produce better
results than an ad-hoc answer. When in doubt, invoke the skill. A false positive is
cheaper than a false negative.
Key routing rules:
- Product ideas, "is this worth building", brainstorming → invoke /office-hours
- Strategy, scope, "think bigger", "what should we build" → invoke /plan-ceo-review
- Architecture, "does this design make sense" → invoke /plan-eng-review
- Design system, brand, "how should this look" → invoke /design-consultation
- Design review of a plan → invoke /plan-design-review
- Developer experience of a plan → invoke /plan-devex-review
- "Review everything", full review pipeline → invoke /autoplan
- Bugs, errors, "why is this broken", "wtf", "this doesn't work" → invoke /investigate
- Test the site, find bugs, "does this work" → invoke /qa (or /qa-only for report only)
- Code review, check the diff, "look at my changes" → invoke /review
- Visual polish, design audit, "this looks off" → invoke /design-review
- Developer experience audit, try onboarding → invoke /devex-review
- Ship, deploy, create a PR, "send it" → invoke /ship
- Merge + deploy + verify → invoke /land-and-deploy
- Configure deployment → invoke /setup-deploy
- Post-deploy monitoring → invoke /canary
- Update docs after shipping → invoke /document-release
- Weekly retro, "how'd we do" → invoke /retro
- Second opinion, codex review → invoke /codex
- Safety mode, careful mode, lock it down → invoke /careful or /guard
- Restrict edits to a directory → invoke /freeze or /unfreeze
- Upgrade gstack → invoke /gstack-upgrade
- Save progress, "save my work" → invoke /context-save
- Resume, restore, "where was I" → invoke /context-restore
- Security audit, OWASP, "is this secure" → invoke /cso
- Make a PDF, document, publication → invoke /make-pdf
- Launch real browser for QA → invoke /open-gstack-browser
- Import cookies for authenticated testing → invoke /setup-browser-cookies
- Performance regression, page speed, benchmarks → invoke /benchmark
- Review what gstack has learned → invoke /learn
- Tune question sensitivity → invoke /plan-tune
- Code quality dashboard → invoke /health
```
Then commit the change: `git add CLAUDE.md && git commit -m "chore: add gstack skill routing rules to CLAUDE.md"`
If B: run `~/.claude/skills/gstack/bin/gstack-config set routing_declined true`
Say "No problem. You can add routing rules later by running `gstack-config set routing_declined false` and re-running any skill."
This only happens once per project. If `HAS_ROUTING` is `yes` or `ROUTING_DECLINED` is `true`, skip this entirely.
If `VENDORED_GSTACK` is `yes`: This project has a vendored copy of gstack at
`.claude/skills/gstack/`. Vendoring is deprecated. We will not keep vendored copies
up to date, so this project's gstack will fall behind.
Use AskUserQuestion (one-time per project, check for `~/.gstack/.vendoring-warned-$SLUG` marker):
> This project has gstack vendored in `.claude/skills/gstack/`. Vendoring is deprecated.
> We won't keep this copy up to date, so you'll fall behind on new features and fixes.
>
> Want to migrate to team mode? It takes about 30 seconds.
Options:
- A) Yes, migrate to team mode now
- B) No, I'll handle it myself
If A:
1. Run `git rm -r .claude/skills/gstack/`
2. Run `echo '.claude/skills/gstack/' >> .gitignore`
3. Run `~/.claude/skills/gstack/bin/gstack-team-init required` (or `optional`)
4. Run `git add .claude/ .gitignore CLAUDE.md && git commit -m "chore: migrate gstack from vendored to team mode"`
5. Tell the user: "Done. Each developer now runs: `cd ~/.claude/skills/gstack && ./setup --team`"
If B: say "OK, you're on your own to keep the vendored copy up to date."
Always run (regardless of choice):
```bash
eval "$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)" 2>/dev/null || true
touch ~/.gstack/.vendoring-warned-${SLUG:-unknown}
```
This only happens once per project. If the marker file exists, skip entirely.
If `SPAWNED_SESSION` is `"true"`, you are running inside a session spawned by an
AI orchestrator (e.g., OpenClaw). In spawned sessions:
- Do NOT use AskUserQuestion for interactive prompts. Auto-choose the recommended option.
- Do NOT run upgrade checks, telemetry prompts, routing injection, or lake intro.
- Focus on completing the task and reporting results via prose output.
- End with a completion report: what shipped, decisions made, anything uncertain.

[ -f "$_GSTACK_HOME/.brain-last-push" ] && _BRAIN_LAST_PUSH=$(cat "$_GSTACK_HOME/.brain-last-push" 2>/dev/null || echo never)
echo "BRAIN_SYNC: mode=$_BRAIN_SYNC_MODE | last_push=$_BRAIN_LAST_PUSH | queue=$_BRAIN_QUEUE_DEPTH"
else
echo "BRAIN_SYNC: off"
fi
```
**Privacy stop-gate (fires ONCE per machine).**
If the bash output shows `BRAIN_SYNC: off` AND the config value
`gbrain_sync_mode_prompted` is `false` AND gbrain is detected on this host
(either `gbrain doctor --fast --json` succeeds or the `gbrain` binary is in PATH),
fire a one-time privacy gate via AskUserQuestion:
> gstack can publish your session memory (learnings, plans, designs, retros) to a
> private GitHub repo that GBrain indexes across your machines. Higher tiers
> include behavioral data (session timelines, developer profile). How much do you
> want to sync?
Options:
- A) Everything allowlisted (recommended — maximum cross-machine memory)
- B) Only artifacts (plans, designs, retros, learnings) — skip timelines and profile
- C) Decline — keep everything local
After the user answers, run (substituting the chosen value):
```bash
# Chosen mode: full | artifacts-only | off
"$_BRAIN_CONFIG_BIN" set gbrain_sync_mode <choice>
"$_BRAIN_CONFIG_BIN" set gbrain_sync_mode_prompted true
```
If A or B was chosen AND `~/.gstack/.git` doesn't exist, ask a follow-up:
"Set up the GBrain sync repo now? (runs `gstack-brain-init`)"
- A) Yes, run it now
- B) Show me the command, I'll run it myself
Do not block the skill. Emit the question, continue the skill workflow. The
next skill run picks up wherever this left off.
**At skill END (before the telemetry block),** run these bash commands to
catch artifact writes (design docs, plans, retros) that skipped the writer
shims, plus drain any still-pending queue entries:
```bash
"~/.claude/skills/gstack/bin/gstack-brain-sync" --discover-new 2>/dev/null || true
"~/.claude/skills/gstack/bin/gstack-brain-sync" --once 2>/dev/null || true
```
## Model-Specific Behavioral Patch (claude)
The following nudges are tuned for the claude model family. They are
**subordinate** to skill workflow, STOP points, AskUserQuestion gates, plan-mode
safety, and /ship review gates. If a nudge below conflicts with skill instructions,
the skill wins. Treat these as preferences, not rules.
**Todo-list discipline.** When working through a multi-step plan, mark each task
complete individually as you finish it. Do not batch-complete at the end. If a task
turns out to be unnecessary, mark it skipped with a one-line reason.
**Think before heavy actions.** For complex operations (refactors, migrations,
non-trivial new features), briefly state your approach before executing. This lets
the user course-correct cheaply instead of mid-flight.
**Dedicated tools over Bash.** Prefer Read, Edit, Write, Glob, Grep over shell
equivalents (cat, sed, find, grep). The dedicated tools are cheaper and clearer.
## Voice
**Tone:** direct, concrete, sharp, never corporate, never academic. Sound like a builder, not a consultant. Name the file, the function, the command. No filler, no throat-clearing.
**Writing rules:** No em dashes (use commas, periods, "..."). No AI vocabulary (delve, crucial, robust, comprehensive, nuanced, etc.). Short paragraphs. End with what to do.
The user always has context you don't. Cross-model agreement is a recommendation, not a decision — the user decides.
## Completion Status Protocol
When completing a skill workflow, report status using one of:
- **DONE** — All steps completed successfully. Evidence provided for each claim.
- **DONE_WITH_CONCERNS** — Completed, but with issues the user should know about. List each concern.
- **BLOCKED** — Cannot proceed. State what is blocking and what was tried.
- **NEEDS_CONTEXT** — Missing information required to continue. State exactly what you need.
### Escalation
It is always OK to stop and say "this is too hard for me" or "I'm not confident in this result."
Bad work is worse than no work. You will not be penalized for escalating.
- If you have attempted a task 3 times without success, STOP and escalate.
- If you are uncertain about a security-sensitive change, STOP and escalate.
- If the scope of work exceeds what you can verify, STOP and escalate.
Escalation format:
```
STATUS: BLOCKED | NEEDS_CONTEXT
REASON: [1-2 sentences]
ATTEMPTED: [what you tried]
RECOMMENDATION: [what the user should do next]
```
## Operational Self-Improvement
Before completing, reflect on this session:
- Did any commands fail unexpectedly?
- Did you take a wrong approach and have to backtrack?
- Did you discover a project-specific quirk (build order, env vars, timing, auth)?
- Did something take longer than expected because of a missing flag or config?
If yes, log an operational learning for future sessions:
```bash
~/.claude/skills/gstack/bin/gstack-learnings-log '{"skill":"SKILL_NAME","type":"operational","key":"SHORT_KEY","insight":"DESCRIPTION","confidence":N,"source":"observed"}'
```
Replace SKILL_NAME with the current skill name. Only log genuine operational discoveries.
Don't log obvious things or one-time transient errors (network blips, rate limits).
A good test: would knowing this save 5+ minutes in a future session? If yes, log it.
## Telemetry (run last)
After the skill workflow completes (success, error, or abort), log the telemetry event.
Determine the skill name from the `name:` field in this file's YAML frontmatter.
Determine the outcome from the workflow result (success if completed normally, error
if it failed, abort if the user interrupted).
**PLAN MODE EXCEPTION — ALWAYS RUN:** This command writes telemetry to
`~/.gstack/analytics/` (user config directory, not project files). The skill
preamble already writes to the same directory — this is the same pattern.
Skipping this command loses session duration and outcome data.
Run this bash:
```bash
_TEL_END=$(date +%s)
_TEL_DUR=$(( _TEL_END - _TEL_START ))
rm -f ~/.gstack/analytics/.pending-"$_SESSION_ID" 2>/dev/null || true
# Session timeline: record skill completion (local-only, never sent anywhere)
~/.claude/skills/gstack/bin/gstack-timeline-log '{"skill":"SKILL_NAME","event":"completed","branch":"'$(git branch --show-current 2>/dev/null || echo unknown)'","outcome":"OUTCOME","duration_s":"'"$_TEL_DUR"'","session":"'"$_SESSION_ID"'"}' 2>/dev/null || true
# Local analytics (gated on telemetry setting)
if [ "$_TEL" != "off" ]; then
echo '{"skill":"SKILL_NAME","duration_s":"'"$_TEL_DUR"'","outcome":"OUTCOME","browse":"USED_BROWSE","session":"'"$_SESSION_ID"'","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'"}' >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true
fi
# Remote telemetry (opt-in, requires binary)
if [ "$_TEL" != "off" ] && [ -x ~/.claude/skills/gstack/bin/gstack-telemetry-log ]; then
~/.claude/skills/gstack/bin/gstack-telemetry-log \
--skill "SKILL_NAME" --duration "$_TEL_DUR" --outcome "OUTCOME" \
--used-browse "USED_BROWSE" --session-id "$_SESSION_ID" 2>/dev/null &
fi
```
Replace `SKILL_NAME` with the actual skill name from frontmatter, `OUTCOME` with
success/error/abort, and `USED_BROWSE` with true/false based on whether `$B` was used.
If you cannot determine the outcome, use "unknown". The local JSONL always logs. The
remote binary only runs if telemetry is not off and the binary exists.
## Plan Mode Safe Operations
In plan mode, these are always allowed (they inform the plan, don't modify source):
`$B` (browse), `$D` (design), `codex exec`/`codex review`, writes to `~/.gstack/`,
writes to the plan file, `open` for generated artifacts.
## Skill Invocation During Plan Mode
If the user invokes a skill in plan mode, that skill takes precedence over generic plan mode behavior. Treat it as executable instructions, not reference. Follow step
by step. AskUserQuestion calls satisfy plan mode's end-of-turn requirement. At a STOP
point, stop immediately. Do not continue the workflow past a STOP point and do not call ExitPlanMode there. Commands marked "PLAN
MODE EXCEPTION — ALWAYS RUN" execute. Other writes need to be already permitted
above or explicitly exception-marked. Call ExitPlanMode only after the skill
workflow completes — only then call ExitPlanMode (or if the user tells you to cancel the skill or leave plan mode).
## Plan Status Footer
In plan mode, before ExitPlanMode: if the plan file lacks a `## GSTACK REVIEW REPORT`
section, run `~/.claude/skills/gstack/bin/gstack-review-read` and append a report.
With JSONL entries (before `---CONFIG---`), format the standard runs/status/findings
table. With `NO_REVIEWS` or empty, append a 5-row placeholder table (CEO/Codex/Eng/
Design/DX Review) with all zeros and verdict "NO REVIEWS YET — run `/autoplan`".
If a richer review report already exists, skip — review skills wrote it.
PLAN MODE EXCEPTION — always allowed (it's the plan file).
# make-pdf: publication-quality PDFs from markdown
Turn `.md` files into PDFs that look like Faber & Faber essays: 1in margins,
left-aligned body, Helvetica throughout, curly quotes and em dashes, optional
cover page and clickable TOC, diagonal DRAFT watermark when you need it.
Copy-paste from the PDF produces clean words, never "S a i l i n g".
On Linux, install `fonts-liberation` for correct rendering — Helvetica and Arial
aren't present by default, and Liberation Sans is the standard metric-compatible
fallback. CI and Docker builds install it automatically via Dockerfile.ci.
## MAKE-PDF SETUP (run this check BEFORE any make-pdf command)
```bash
_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
P=""
[ -n "$MAKE_PDF_BIN" ] && [ -x "$MAKE_PDF_BIN" ] && P="$MAKE_PDF_BIN"
[ -z "$P" ] && [ -n "$_ROOT" ] && [ -x "$_ROOT/.claude/skills/gstack/make-pdf/dist/pdf" ] && P="$_ROOT/.claude/skills/gstack/make-pdf/dist/pdf"
[ -z "$P" ] && P="$HOME/.claude/skills/gstack/make-pdf/dist/pdf"
if [ -x "$P" ]; then
echo "MAKE_PDF_READY: $P"
alias _p_="$P" # shellcheck alias helper (not exported)
export P # available as $P in subsequent blocks within the same skill invocation
else
echo "MAKE_PDF_NOT_AVAILABLE (run './setup' in the gstack repo to build it)"
fi
```
If `MAKE_PDF_NOT_AVAILABLE` is printed: tell the user the binary is not
built. Have them run `./setup` from the gstack repo, then retry.
If `MAKE_PDF_READY` is printed: `$P` is the binary path for the rest of
the skill. Use `$P` (not an explicit path) so the skill body stays portable.
Core commands:
- `$P generate <input.md> [output.pdf]` — render markdown to PDF (80% use case)
- `$P generate --cover --toc essay.md out.pdf` — full publication layout
- `$P generate --watermark DRAFT memo.md draft.pdf` — diagonal DRAFT watermark
- `$P preview <input.md>` — render HTML and open in browser (fast iteration)
- `$P setup` — verify browse + Chromium + pdftotext and run a smoke test
- `$P --help` — full flag reference
Output contract:
- `stdout`: ONLY the output path on success. One line.
- `stderr`: progress (`Rendering HTML... Generating PDF...`) unless `--quiet`.
- Exit 0 success / 1 bad args / 2 render error / 3 Paged.js timeout / 4 browse unavailable.
## Core patterns
### 80% case — memo/letter
One command, no flags. Gets a clean PDF with running header + page numbers
+ CONFIDENTIAL footer by default.
```bash
$P generate letter.md # writes /tmp/letter.pdf
$P generate letter.md letter.pdf # explicit output path
```
### Publication mode — cover + TOC + chapter breaks
```bash
$P generate --cover --toc --author "Garry Tan" --title "On Horizons" \
essay.md essay.pdf
```
Each top-level H1 in the markdown starts a new page. Disable with
`--no-chapter-breaks` for memos that happen to have multiple H1s.
### Draft-stage watermark
```bash
$P generate --watermark DRAFT memo.md draft.pdf
```
Diagonal 10% opacity DRAFT across every page. When the draft is final, drop
the flag and regenerate.
### Fast iteration via preview
```bash
$P preview essay.md
```
Renders HTML with the same print CSS and opens it in your browser. Refresh
as you edit the markdown. Skip the PDF round trip until you're ready.
### Brand-free (no CONFIDENTIAL footer)
```bash
$P generate --no-confidential memo.md memo.pdf
```
## Common flags
```
Page layout:
--margins <dim> 1in (default) | 72pt | 2.54cm | 25mm
--page-size letter|a4|legal
Structure:
--cover Cover page (title, author, date, hairline rule)
--toc Clickable TOC with page numbers
--no-chapter-breaks Don't start a new page at every H1
Branding:
--watermark <text> Diagonal watermark ("DRAFT", "CONFIDENTIAL")
--header-template <html> Custom running header
--footer-template <html> Custom footer (mutex with --page-numbers)
--no-confidential Suppress the CONFIDENTIAL right-footer
Output:
--page-numbers "N of M" footer (default on)
--tagged Accessible PDF (default on)
--outline PDF bookmarks from headings (default on)
--quiet Suppress progress on stderr
--verbose Per-stage timings
Network:
--allow-network Fetch external images. Off by default
(blocks tracking pixels).
Metadata:
--title "..." Document title (defaults to first H1)
--author "..." Author for cover + PDF metadata
--date "..." Date for cover (defaults to today)
```
## When Claude should run it
Watch for markdown-to-PDF intent. Any of these patterns → run `$P generate`:
- "Can you make this markdown a PDF"
- "Export it as a PDF"
- "Turn this letter into a PDF"
- "I need a PDF of the essay"
- "Print this as a PDF for me"
If the user has a `.md` file open and says "make it look nice", propose
`$P generate --cover --toc` and ask before running.
## Debugging
- Output looks empty / blank → check browse daemon is running: `$B status`.
- Fragmented text on copy-paste → highlight.js output (Phase 4). Retry with
`--no-syntax` once that flag exists. For now, remove fenced code blocks
and regenerate.
- Paged.js timeout → probably no headings in the markdown. Drop `--toc`.
- External image missing → add `--allow-network` (understand you're giving
the markdown file permission to fetch from its image URLs).
- Generated PDF too tall/wide → `--page-size a4` or `--margins 0.75in`.
## Output contract
```
stdout: /tmp/letter.pdf ← just the path, one line
stderr: Rendering HTML... ← progress spinner (unless --quiet)
Generating PDF...
Done in 1.5s. 43 words · 22KB · /tmp/letter.pdf
exit code: 0 success / 1 bad args / 2 render error / 3 Paged.js timeout
/ 4 browse unavailable
```
Capture the path: `PDF=$($P generate letter.md)` — then use `$PDF`.
