Garry Tanandcapy-ai[bot] 3e4240a76f v1.91.276.0 feat(preamble): tier 2+ skills load the shared preamble once per session (GSTA-96) (#3434)
* fix(preamble): completeness means complete coverage with minimal code (GSTA-96)

* feat(preamble): tier 2+ skills load the shared preamble once per session (GSTA-96)

Every tier 2+ SKILL.md inlined the same ~23 KB preamble. It now renders once
per host into sections/preamble.md beside each tier 2+ SKILL.md; the SKILL.md
keeps a pointer that asks for the Read only when the file's id is not already
in context. Only sections byte-identical to the shared render move, so every
skill keeps exactly its pre-hoist paragraphs (verified across all 41 skills).

Parity caps for ten skills raised to their measured unions (owner-approved,
Garry 2026-10-25: "do it"); 63 size pins lowered and 26 deleted.

* fix(paid-select): a generated sections/preamble.md takes its skill template's identity in the PR planner (GSTA-96)

screen-summary failed on #3434 with 'PR profile requires full validation' for nine
skills whose only paid coverage is periodic: their new sections/preamble.md had no
dependency identity, while the SKILL.md beside it inherits its template's.

* test(section-manifest): the shared sections/preamble.md renders from the hoist resolver, not a section template (GSTA-96)

* fix: pre-landing review fixes (CHANGELOG says 3 characters shorter; model-overlays guards the coverage half)

The completeness section shrank by 3 characters (5 bytes), matching the 89 pins lowered by 3. The default-copy test pinned only the minimal-code half; an expectMentions check now fails if the full-coverage or never-excuses-a-gap clause is dropped.

* fix: pre-landing review fixes (model-overlays binds smaller diff to equal coverage)

The default-copy check now also fails if 'on equal coverage' is dropped from the smaller-diff rule (which would tell models to prefer the smaller diff unconditionally) or if the no-impossible-state-checks clause is removed.

* docs: CHANGELOG lists the model-overlays coverage checks

The [Unreleased] Tests bullet now says the default-copy test checks both halves of the rule (full coverage of the requirement; smaller diff only at equal coverage; no impossible-state checks; never excuses a gap), matching 88e3cc0 and 44eacaf.

* test: cover the shared-preamble hoist (ship Step 7)

Adds test/preamble-hoist.test.ts (tier 1 unchanged; tier 2+ SKILL.md plus
sections/preamble.md reproduces the pre-hoist preamble; pointer position and id)
and two gen-skill-docs-checks cases (one shared preamble per host, beside every
pointer and named by its id; preamble artifact kind).

* fix: pre-landing review fixes (ship Step 9.4)

- setup: follow a symlinked sections/ dir in the carved-pointer status check
- touchfiles: select preamble-hoist.ts alongside every preamble.ts entry
- section-manifest: exempt sections/preamble.md only for skills whose SKILL.md
  carries the shared-preamble pointer
- skill-size-budget: growth ceiling measures SKILL.md plus its shared preamble
- host-conformance: tolerate a missing sections/ dir, as setup does
- skill-validation: read bin/gstack-skill-start directly
- skill-fixture: error messages and docblocks name the actual boundary
  (harness-version non-behavioral note updated)

* fix: describe the size-budget growth check's startup measure (ship Step 9.4, pass 2)

The growth ceiling now measures SKILL.md plus the shared preamble, the same
measure as the shrink floor; the docblock said SKILL.md only.

* test: cover the symlinked sections/ status check and the ETHOS house-rule quote (ship Step 7)

host-conformance: --status still finds a broken bare sections/ pointer when a
carved Claude skill's installed sections/ is a directory symlink (fails at the
pre-repair 0e5d11fd9). gen-skill-docs: the house rule review/specialists/
simplification.md quotes from ETHOS.md still appears in ETHOS.md.

* fix: the shared-preamble skip needs the skill's own Read; digest and first-run intro say complete coverage, minimal code (GSTA-96)

The pointer skipped the shared file when any text carrying its id was in context, so a
page or file with that heading could stand in for the anti-spoofing rules (security,
red team and adversarial review, ship run 2). It now requires the skill's own earlier
Read. The digest's Boil the Ocean bullet and the first-run intro still said 'AI makes
completeness cheap, so do the complete thing' (docs audit blocker); both now carry
Garry's 'complete coverage, minimal code' (2026-10-25: '1/ yes fix this').

* test: pin the shared-preamble provenance skip and the new Boil the Ocean wording (ship Step 7)

preamble-hoist: on every host, tier and render option the pointer allows the
skip only when the skill's own Read is in context. agents-digest and
gstack-skill-start: the digest bullet and the lake intro say complete
coverage, minimal code, never the retired phrasing. Each fails at 9af36d010.

* fix: describe the provenance skip where the docs still described the id-only one (ship Step 9.4)

The preamble-hoist.ts docblock and ARCHITECTURE.md still said the shared
preamble is re-read only when its id is absent; since 2acf1a44a the pointer
requires the skill's own earlier Read of the file.

* revert(digest): keep the agents digest at main's bytes; an unstamped head cannot change a release output (GSTA-96)

CI 'Check VERSION is not stale vs queue' classified #3434 as stamped because it touched
agents-digest/gstack-AGENTS.md (a release_outputs path), while regenerating only the
generator fails the digest freshness test. The first-run intro rewording stays.

* test: refresh the claude ship golden the main merge took from main (ship Step 5 preflight)

The 1a4dcaf07 merge resolved test/fixtures/golden/claude-ship-SKILL.md to
main's pre-hoist bytes. The golden is a copy of ship/SKILL.md; regenerated
with bun scripts/gen-ship-goldens.ts (pregate regen: REGEN_STALE).

* test: pr-dependencies' unplaceable-file example uses SECURITY.md now that ETHOS.md is mapped

6183ca8ae registered ETHOS.md on its reader cases in touchfiles-data.ts, so a
PR touching only ETHOS.md plans in pr mode and no longer restores the full gate.
The fail-closed test and the real-unknown label check now use SECURITY.md, which
is tracked and unmapped; the assertions are unchanged. CHANGELOG names the
third test file. (CI free shard 7 at 7c21720ac; remote pregate shard 6.)

* test: host path-leak checks read the moved shared preamble too; name SHARED_PREAMBLE_FILE (ship review pass 2)

The external-host path-leak assertions in gen-skill-docs.test.ts (Codex,
Factory) and host-config.test.ts (Copilot, Antigravity) read SKILL.md
alone, so a Claude path that moved into sections/preamble.md with the
hoist went unchecked. They now read the skill's startup text through
readSkillStartup. workflow-judge-input and host-conformance use the
SHARED_PREAMBLE_FILE constant instead of a bare 'preamble.md' literal,
and preamble.ts's header describes the hoisted composition.

* docs: CHANGELOG token savings name the per-skill skip and the autoplan follow-up (ship review pass 2)

The pointer's skip is bound to the skill's own copy of sections/preamble.md,
so "every later one saves about 5,800" holds per skill, not per session, and
/autoplan's skip list and the inline /office-hours loader do not yet skip the
pointer section. The entry now says so instead of claiming the full /autoplan
saving. Adding the skip entry grows size-pinned skills, so it is a follow-up.

* test: corpus budget measures startup bytes; carve-safety counts shared preamble as uncarved (ship review pass 2)

skill-size-budget's growth ceiling and shrink floor already measured
SKILL.md plus sections/preamble.md, but the total-corpus check still summed
hoisted SKILL.md bytes against the pre-hoist baseline, hiding about 0.9 MB
of headroom. It now sums the same startup bytes (3,114,885 -> 2,590,484,
x0.832); the unreachable SKILL.md-missing fallback is gone.

auq-format-always-loaded's carve-safety guard treated any sections/ dir as
carved, so every skill with only the shared preamble ran it and its sanity
check passed on preamble.md. It now uses setup --status's rule: a section
other than the shared preamble. Those skills keep the per-skill checks.

* test: remaining SKILL.md-only negatives read the shared preamble too (ship review pass 3)

The parameterized external-host path-leak smoke test, the two Codex
.claude path checks and both vestigial-handshake negatives read SKILL.md
alone, so text that moved into sections/preamble.md went unchecked. They
now read readSkillStartup. preamble.ts's header no longer says tier 1
renders through generatePreamble().

* test: ratchet skeleton caps and eager context ceilings down after the hoist (ship review pass 3)

The hoist moved about 22 KB out of every tier 2+ SKILL.md, which left
each hoisted maxSkeletonBytes cap and each eagerPerInvocation ceiling
roughly 22 KB / 5-6K tokens slack. The 20 hoisted skeleton caps now sit at
the post-hoist skeleton plus their pre-hoist headroom, and 42 context-budget
ceilings take the recaptured (lower) values. Nothing was raised: the four
ceilings the recapture would have raised keep their old values.

* fix: preamble-hoist's section splitter closes a fence only on a bare delimiter (ship Step 11)

Inside an open fence, a line such as "```bash" is content in CommonMark,
but splitSections treated it as the closing fence, so a later "## " line in
the same block could split a section mid-code-block and hoist half of it.
A closing delimiter now needs nothing but whitespace after it. Every host's
render is unchanged (gen-skill-docs --dry-run FRESH on all twelve hosts).

* test: skill-startup.ts is a global, pinned harness file like skill-fixture.ts (ship review pass 3)

skill-fixture.ts is a global touchfile pinned in scripts/harness-version.json
because it reshapes the skill content most E2E suites read, and it now
builds that content through test/helpers/skill-startup.ts. That helper was
in neither list, so a later edit to it would change fixture inputs without
the harness-version guard and select only 27 keys. It is now global and
pinned, recorded non-behavioral (its fixtures are byte-identical to the
pre-hoist output). ARCHITECTURE.md and the CHANGELOG stop calling the
pointer id a content id: it hashes the shared text before host rewrites.

* docs: CHANGELOG matches the merged skip lists and the baseline diff (ship review, run 4)

The headline still called the autoplan and inline /office-hours skip
entries a follow-up, but the main merge added them; it now says the loaded
skills skip their shared Read. The #3451 sentence is dropped, because that
fix shipped in v1.91.237.0 and is recorded there. The typecheck baseline
line says the TS2769 entry was re-keyed for the 'preamble' artifact kind
with its count unchanged, not fixed and lowered.

* test: pin the pointer entry in the loader skip lists; drop a carve-safety tautology (ship review, run 4)

A new INVOKE_SKILL test checks that plan-ceo-review's inline /office-hours
skip list and autoplan's section skip list both name the shared-preamble
pointer heading, and that office-hours and the four plan reviews carry it.
The carve-safety "sanity" assertion repeated the predicate discoverSkills()
now uses to set sectionsDir, so it could never fail; it is removed.

* fix: gstack-doctor finds the Codex model patch in the hoisted shared preamble (ship Step 11, run 4)

The doctor's patch row grepped only the Codex review SKILL.md for the
"Model-Specific Behavioral Patch (" heading. The hoist moves that section
into sections/preamble.md, so the required row (for ship, review, the plan
reviews, office-hours, investigate and more) would fail on every correct
post-hoist Codex install and block install.sh's "gstack: ok". It now checks
the SKILL.md and then its shared preamble and names the file it found. A
new doctor test covers a hoisted render.

preamble-hoist's variantSubsections also returns null when no subsection
differs, instead of emitting a replacing heading with no subsections.
Every host's render is unchanged.

* test(docsync): fixtureDocs installs the generated sections/preamble.md (hunk taken from #3472)

A generated skill that loads the shared preamble names sections/preamble.md
as a required asset before skill start, and a spawned document-release child
blocks on its absence, so docsync-spawned stayed red on every #3434 screen.
fixtureDocs now copies that file when the generated skill has it.

This single hunk is taken unchanged from gstack#3472 (head 2e3f7ba1,
GSTA-107), which trains ahead of #3434, so the train merge sees identical
lines. Nothing else from #3472 is included.
