Garry Tanandcapy-ai[bot] 021d817c36 v1.91.240.0 feat(proactive): default to the four core skills (core | all | off), with docs, prompt and tests (GSTA-99) (#3432)
* feat(proactive): default to the four core skills (core | all | off); docs, prompt and tests (GSTA-99)

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix(proactive): gstack-skill-start falls back to core, not true, when gstack-config is missing

The PROACTIVE status line's fallback literal still said true (= all) after the default moved to core. Found by /ship's coverage audit; the regression test fails at the previous head and passes at main.

* test(proactive): STATUS line carries the stored value; every surface names the same core four and three values

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix(proactive): off gates the office-hours handoff; the preamble and router scope the setting to unasked suggestions

The office-hours next-review handoff gated on the legacy false only, so an off user was still asked to launch /plan-eng-review. The per-skill preamble now says the setting governs unasked suggestions and this skill's own steps still run (a handoff, a review gate, a dispatched /document-release is not a suggestion), at exactly the previous length, so the 89 size pins return to main's values; the router says the same in full. Found by /ship's specialist and red-team review.

* fix(skill-start): unknown proactive values read as core; first-run tips name core skills and stay quiet under off

A hand-edited config can hold any value and only set validates, so STATUS normalizes anything but core|all|off|true|false to core. The first-run and first-loop tips named /spec, /investigate and /plan-eng-review whatever the setting; they now name the core four and are skipped under off. The fallback regression test folds into test/proactive-skill-start.test.ts, the duplicate header assertion leaves proactive-config, and the frozen-length preamble test is retired (the size guard enforces it).

* docs(proactive): scope note, the unknown-value rule, and the CLAUDE.md routing follow-up; CHANGELOG

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix(skill-start): no CLAUDE.md routing offer under proactive off

The one-time offer to append ## Skill routing to the project's CLAUDE.md fired whatever the proactive value, and its rules are the auto-invocation an off user turned off. The offer is skipped under off and the legacy false; a section already in CLAUDE.md is left alone. Under core the offered section still routes every skill, which docs/proactive.md records as the follow-up. Found by /ship's red team.

* fix(proactive): STATUS says only core | all | off, and the preamble carves out only named skills

gstack-skill-start reads the legacy true/false as all/off and tolerates a quoted, upper-case or commented hand edit (proactive: OFF # mine read as core before), so every surface sees one of three values and the off gating lives in one flag. The per-skill preamble drops the legacy spellings and replaces 'This skill's steps still run', which licensed any in-skill offer under off, with 'Skills the user or this skill's steps name run', at the same length, so the 89 size pins stay at main's. Tests run the script for the tips and the routing offer under core and off instead of grepping the source. Found by /ship's fix-range repeat (red team, testing, maintainability).

* fix(config): set proactive is case-insensitive; follow-up #3446 cited; test hygiene

set proactive OFF warned and stored core, the opposite of the opt-out typed; the value is lowercased first, as gstack-skill-start does for a hand edit. The fixture git init carries the tripwire timeout, the source-shape assertion on the private _PROACTIVE_OFF line goes (the routing-offer test proves the behavior), and the CHANGELOG Tests bullets collapse to one per file with the known gap pointing at #3446. Found by /ship's full repeat pass and its tests lane.

* fix(proactive): a stored off answers the one-time prompt; the router names /browse and /investigate under core instead of invoking them

Red team, full repeat pass: with proactive: off stored before the prompt, skill-start still emitted the opt-in prompt; it now writes the marker and asks nothing. The router's Route-first browser step and the Failures branches invoked non-core skills under core while the core block said to answer directly; one sentence in the core block resolves it, pinned by the core-set tests. CHANGELOG and docs/proactive.md say both.

* docs(proactive): the full-catalog skill descriptions are the second surface that still routes every skill under core (#3446)

From /ship's document-release audit: a --catalog-mode=full build and the non-Claude hosts keep the "Proactively suggest when ..." description sentences, which do not follow the setting; the default Claude build trims them.

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* test(proactive): the tips test runs skill-start as an interactive session

GitHub CI sets CI/GITHUB_ACTIONS, which gstack-session-kind reads as headless, and a headless start skips first-task detection, so the first-run tip never fires there (Free Tests shard 16 red at 0d7dbe6; green locally and on the Ubicloud pregate, which have no CI marker). The fixture now sets CLAUDE_CODE_ENTRYPOINT=cli, the positive interactive signal; reproduced locally with CI=1 and fixed.

* fix(proactive): an opt-out never fails open; the preamble carves out invocations, not offers

The YAML yes/no family (yes/on/1, no/none/0/disabled/never) reads as all/off in both gstack-skill-start and gstack-config set, so a typed or hand-edited opt-out cannot land on core. The per-skill preamble says "Skills the user names or this one invokes run" (same 168-char length, pins unchanged): a skill dispatching another is not a suggestion, an in-skill offer to run one still is under off. The stored-off prompt marker is written before STATUS prints PROACTIVE_PROMPTED, so the line is true. docs/proactive.md's table row carves out in-skill handoffs.

Fourth /ship fix cycle, past the skill's three-cycle cap by GStack Minder's decision (2026-10-26) under Garry's "do it" on the proactive core set; items from the Step 11 adversarial pass.

# Docs: https://github.com/garrytan/gstack
#
# ─── Behavior ────────────────────────────────────────────────────────
# proactive: core # core = auto-invoke only /office-hours, /review, /qa and /ship
# # when your request matches one; every other skill waits
# # for you to type it. all = auto-invoke any matching skill.
# # off = only run skills you type explicitly.
# # (true and false still work: true means all, false means off.)
#
# routing_declined: false # Set to true to skip the CLAUDE.md routing injection
# # prompt. Set back to false to be asked again.
#
# ─── Telemetry ───────────────────────────────────────────────────────
# telemetry: off # off | anonymous | community
# # off — no data sent, no local analytics (default)
# # anonymous — counter only, no device ID
# # community — usage data + stable device ID
# # Opted in, each skill run is also logged locally to
# # analytics/skill-usage.jsonl under this state root
# # with the repo name and branch; those two fields are
# # stripped before upload. Off logs nothing there.
#
# ─── Session markers (local functional state, not telemetry) ─────────
# sessions/<pid> # One empty file per live agent session, touched at
# # skill start and deleted after 120 minutes. The
# # count tells skills when several sessions share a
# # machine. Never sent anywhere; not gated on
# # telemetry.
#
# ─── Updates ─────────────────────────────────────────────────────────
# auto_upgrade: false # true = silently upgrade on session start
# update_check: true # false = suppress version check notifications
# update_channel: auto # auto = stable when team_mode is true, else main
# # stable = the weekly tagged release (refs/heads/stable)
# # main = every merge to main (docs/releases.md)
#
# ─── Skill naming ────────────────────────────────────────────────────
# skill_prefix: false # true = namespace skills as /gstack-qa, /gstack-ship
# # false = short names /qa, /ship
# disabled_skills: # comma-separated skills to leave unregistered,
# # e.g. make-pdf,pair-agent ("" = all enabled)
#
# ─── Writing style (V1) ──────────────────────────────────────────────
# explain_level: default # default = jargon-glossed, outcome-framed prose
# # (V1 default — more accessible for everyone)
# # terse = V0 prose style, no glosses, no outcome-framing layer
# # (for power users who know the terms)
# # Unknown values default to "default" with a warning.
# # See docs/designs/PLAN_TUNING_V1.md for rationale.
# plan_mode_preamble: on # on = every skill carries the plan-mode preamble
# # off = rendered skills omit the "Plan Mode Safe
# # Operations" and "Skill Invocation During
# # Plan Mode" sections (~1.8 KB each), for
# # users who never enter plan mode
# # Applies on the next ./setup run. Unknown values
# # default to "on" with a warning.
#
# ─── Artifacts sync (renamed from gbrain_sync_mode in v1.27.0.0) ─────
# artifacts_sync_mode: off # off | artifacts-only | full
# # off — no sync (default)
# # artifacts-only — sync plans/designs/retros/learnings only
# # (skip behavioral data: question-log,
# # developer-profile, timeline)
# # full — sync everything allowlisted
# # Set by the first-run privacy stop-gate. See docs/gbrain-sync.md.
#
# artifacts_sync_mode_prompted: false
# # Set to true once the privacy gate has asked the user.
# # Flip back to false to be re-prompted.
#
# artifacts_sync_removals: off # on | off — on: each sync also publishes the
# # removal of synced files gone from disk; more than
# # 20 at once is held for gstack-brain-sync
# # --publish-removals. See docs/gbrain-sync.md.
#
# ─── Transcript ingest (gbrain memory) ───────────────────────────────
# transcript_ingest_mode: off # recent | all | off | new@<UTC> — consent for
# # /sync-gbrain to ingest Claude Code and Codex
# # session transcripts (every project repo policy
# # allows) into your brain (local or Supabase).
# # recent — last 90 days
# # all — all history
# # new@2026-10-03T17:00:00Z — only sessions that
# # start after that UTC time
# # off — never (other memory still syncs)
# # A +repos suffix is kept automatically while
# # transcript_repos is set.
# # Absent, legacy (A-E, incremental) or unknown
# # values are not consent: transcripts are skipped
# # and /sync-gbrain asks once. An invalid value is
# # REJECTED and the stored value kept.
# transcript_repos: # comma-separated git remotes; only transcripts
# # from these repos are ingested. Clear it with
# # `gstack-config unset transcript_repos`.
# # Docs: setup-gbrain/memory.md#transcripts
#
# ─── Timeline Stop hook ──────────────────────────────────────────────
# timeline_stop_hook: yes # Controls whether ./setup registers the timeline
# # Stop hook (closes dangling session entries).
# # yes — register on every setup (default)
# # no — never register; setup also removes a
# # live registration (persistent opt-out;
# # --no-team stays a one-shot teardown, #2677)
#
# ─── Plan-tune hooks ─────────────────────────────────────────────────
# plan_tune_hooks: prompt # Controls whether ./setup installs the plan-tune
# # Claude Code hooks (PostToolUse capture +
# # PreToolUse preference enforcement).
# # prompt — ask on a real TTY, skip otherwise (default)
# # yes — install non-interactively
# # no — skip non-interactively
# # Override per-run: ./setup --plan-tune-hooks /
# # --no-plan-tune-hooks, or env GSTACK_PLAN_TUNE_HOOKS.
#
# ─── Memorable recall bridge (opt-in, third party) ──────────────────
# memorable_recall: off # The gstack-side consent gate for the Memorable
# # UserPromptSubmit bridge (bin/gstack-memorable).
# # off — the hook does nothing, spawns nothing (default)
# # on — the hook hands each prompt to the local
# # `memorable` CLI, receipted as memorable-recall
# # Written by `gstack-memorable enable|disable`. An
# # invalid value is REJECTED and the stored value kept:
# # a typo must never flip a third-party consent.
# # The vendor capture consent (`memorable enable`)
# # is separate; gstack never sets it.
#
# ─── Claude skill overlay ────────────────────────────────────────────
# claude_overlay_model: claude # Claude model ID whose skill overlay ./setup
# # renders (e.g. claude-opus-4-8). Absent = the
# # generic claude overlay. Set it with
# # ./setup --claude-model <id>, which validates the
# # ID and re-renders; ./setup --claude-model claude
# # returns to the generic overlay.
#
# ─── Model policy (gstack-models shows the effective choices) ───────
# Plan review tier: frontier | smart | host. host delegates to the CLI settings;
# GSTACK_CLAUDE_MODEL / GSTACK_CODEX_MODEL still win.
# plan_review_tier: frontier
# Implementation recommendation: frontier | smart. Never switches your session.
# implementation_tier: smart
# Optional pins: model_frontier_claude, model_frontier_openai,
# model_smart_claude and model_smart_openai. Leave pins absent for catalog defaults;
# empty pins are invalid. gstack-models list prints copyable set/unset commands.
# Invalid writes are rejected and preserve the stored value.
# codex_effort: # Codex reasoning effort for outside reviews and /codex:
# # minimal | low | medium | high | xhigh | max | ultra.
# # Absent = every gate keeps its effort. GSTACK_CODEX_EFFORT
# # overrides it per run, /codex --effort per request;
# # /spec keeps medium (120 s budget).
# Docs: docs/model-policy.md
#
# ─── Advanced ────────────────────────────────────────────────────────
# codex_reviews: enabled # Outside review (Codex or Claude Code by harness): sends
# # the review prompt and repository content to that model.
# # enabled (default; the first send prints a notice once):
# # the outside voice of every workflow may run.
# # disabled: the send binaries refuse (not_run,
# # consent_missing) and start no CLI and make no API call;
# # /review, /ship, /autoplan keep native passes; plan and
# # document reviews skip the extra step. Covers design
# # review, /ship design-lite, office hours and /spec.
# # /codex and /claude-code still run when you ask by name.
# # An unreadable config counts as disabled.
# # Invalid values preserve the old value.
# browse_extension_id: # Forks and self-built extensions: the 32-letter (a-p)
# # Chrome extension ID the browse sidebar terminal accepts.
# # Empty = the gstack extension. "" clears it.
# design_detector_install_prompted: false
# # true once you answered the one-time offer from the
# # design skills to download the impeccable engine with
# # "never ask again"; flip back to false to be asked again.
# design_detector: auto # Deterministic design pre-pass through a user-installed
# # impeccable engine (/design-review, /review, /ship,
# # /design-html). auto = use the engine when the probe
# # finds one (gstack never installs or downloads it);
# # off = no probe, no scan, no hint, no /impeccable
# # handoff lines. An invalid value is REJECTED (existing
# # value preserved) so a typo cannot silently disable it.
# gstack_contributor: false # true = file field reports when gstack misbehaves
# skip_eng_review: false # true = skip eng review gate in /ship (not recommended)
#
# ─── Browser extension ───────────────────────────────────────────────
# browse_extension_id: # Chrome extension ID the browse daemon trusts for
# # /extension-token and the terminal-agent /ws
# # (32 letters a-p). Empty = the published gstack
# # extension. Set it only for a fork or a
# # self-built extension; no environment variable
# # or project .env can change it. An invalid value
# # is REJECTED and the stored value kept.
#
# ─── /ship measure-then-fix loop ─────────────────────────────────────
# A red eval case is measured alone before the full gate reruns
# (scripts/ship-measure.ts; docs/TESTING_INTERNALS.md#ship-measure).
# Bar (scripts/lib/measure-bar.ts): MEETS at 9/10 of the trials, MEETS-qualified
# at 8/10 with every red qualifying, EXTEND at 7/10 (one more batch, pooled).
# ship_measure_rule_trials: 10 # rule cases: trials per batch (MEETS 9 of 10)
# ship_measure_behavior_panels: 4 # behavior cases: panels of 3 per batch
# # (12 trials; MEETS 11 of 12)
# ship_measure_judge_outputs: 10 # judge cases: outputs per batch, each scored
# # by its median 3-sample panel (MEETS 9 of 10)
# ship_measure_ask_per_trial_usd: 2 # ask first above this estimated cost per trial
# ship_measure_budget_usd: 25 # estimated admission budget per red case
# # (baseline, extension, redispatch, repair rounds)
# ship_measure_max_rounds: 3 # repair rounds before a named-red stop
# ship_measure_sweep_cases: 5 # weekly off-ship sweep: cases measured (K)
# ship_measure_sweep_budget_usd: 150 # weekly off-ship sweep: spend cap per 7 days
# ship_rerun_backend: local # local | ubicloud — where free-suite flake reruns
# # run; ubicloud also needs UBICLOUD_API_KEY.
# # Invalid values are REJECTED (value kept).
# test_backend: local # local | ubicloud — where the full unit and E2E
# # tiers run (plan E2). The gstack-doctor cores row
# # recommends ubicloud under 8 cores; ubicloud
# # needs UBICLOUD_API_KEY and scripts/ubicloud/.
# # Invalid values are REJECTED (value kept).
# ship_greptile_early: true # true | false — when the repo uses Greptile, /ship
# # pushes and opens a draft PR after its free tests
# # so Greptile reviews in parallel (a public repo
# # asks once). false keeps the old order.
# # Invalid values are REJECTED (value kept).
#
# ─── Workspace-aware ship ────────────────────────────────────────────
# workspace_root: $HOME/conductor/workspaces # Where /ship looks for sibling
# # Conductor worktrees when picking a VERSION slot.
# # Set to "null" to disable sibling scanning entirely.
