v0.36.0.0 feat(skillpack): scaffold + reference + harvest (retire managed-block install) (#1130)

Browse Source 
* feat(skillpack): extract copyArtifacts shared helper (T1)

Pure file-copy primitive for scaffold (gbrain→host) and harvest (host→gbrain).
Atomic-refusal contract: symlink-reject + canonical-path containment validate
every item before any write. Used by both directions of the v0.33 loop.

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

* feat(skillpack): scaffold subcommand + SKILL.md frontmatter sources (T2)

New scaffold.ts replaces the managed-block installer. One-time additive copy
into the user's repo via copyArtifacts; refuses to overwrite existing files
(user owns them). Partial-state policy: copies missing paired sources even
when the skill dir already exists.

bundle.ts extended with loadSkillSources + enumerateScaffoldEntries — paired
source files declared in each SKILL.md's frontmatter sources: array, not in
openclaw.plugin.json. Single source of truth, co-located with the skill.

* feat(skillpack): reference command + apply-clean-hunks (T4 + T15)

reference is the read-only diff lens with an agent-readable framing line. Pure-JS
unified-diff producer + parser + applier (no patch(1) dependency). Two-way merge
with documented limitation: without scaffold-time base tracking, applied hunks
align everything to gbrain. The agent dry-runs reference first, then decides.

* feat(skillpack): migrate-fence + scrub-legacy-fence-rows (T5 + T16)

migrate-fence is the one-shot transition from the pre-v0.36 managed-block model.
Strips begin/end markers and the cumulative-slugs receipt comment; preserves
fence rows verbatim as user-owned routing during the transition to frontmatter
discovery. Receipt-then-row fallback (F-CDX-8) covers stale/missing receipts.

scrub-legacy-fence-rows is the opt-in cleanup after migrate-fence. Two-condition
gate: removes a row only when skills/<slug>/ exists AND that skill's frontmatter
declares non-empty triggers (proof frontmatter discovery covers it).

* feat(skillpack): harvest + privacy linter (T6 + T7)

The inverse loop: lift a proven skill from a host repo (~/git/wintermute, etc.)
back into gbrain so other clients can scaffold it. --from <host-repo-root> is
symmetric with scaffold's --workspace.

Security: symlink rejection + canonical-path containment (mirrors validateUploadPath).
Privacy: default-on linter scans harvested files against ~/.gbrain/harvest-private-patterns.txt
plus built-in defaults (Wintermute, email, Slack channel patterns). Any match
rolls back the copy and exits non-zero. --no-lint bypasses for the editorial
workflow after a manual scrub.

* feat(repo-root): cwd_walk_up tier for non-OpenClaw hosts (T9 + D3)

autoDetectSkillsDir now walks up from cwd looking for any skills/ directory,
ahead of the implicit ~/.openclaw/workspace fallback. cd ~/git/wintermute &&
gbrain skillpack scaffold ... finds wintermute automatically without requiring
a RESOLVER.md/AGENTS.md to exist yet.

R5 regression preserved: $OPENCLAW_WORKSPACE still wins when explicitly set.
+5 test cases in test/repo-root.test.ts pin the new tier order and the R5 guard.

* feat(skillpack): rewrite CLI dispatch, drop install + uninstall (T3 + T10)

skillpack.ts dispatcher rewritten for the v0.36 contract: scaffold, reference
(+ --apply-clean-hunks), migrate-fence, scrub-legacy-fence-rows, harvest, plus
the existing list / diff / check.

install and uninstall are gone — both exit non-zero with a hint pointing at
scaffold / migrate-fence. Clean break, no deprecated alias.

skillpack-check gains --strict for CI gating. When invoked as the subcommand
`gbrain skillpack check`, default is informational (exit 0 even with drift);
--strict opts back into the cron-friendly exit-1-on-issues behavior. Top-level
gbrain skillpack-check preserves its existing exit semantics for backwards compat.

* feat(skills): skillpack-harvest editorial workflow + resolver wiring (T8)

The companion editorial skill for the gbrain skillpack harvest CLI. Walks the
genericization checklist (scrub fork names, generalize triggers, lift fork-
specific conventions to references) before the CLI runs. Routing-eval fixtures
use paraphrased intents to avoid the intent_copies_trigger lint.

Wires the new slug into openclaw.plugin.json#skills, skills/manifest.json, and
skills/RESOLVER.md.

* test(skillpack): 9-case real-subprocess E2E flow (T11)

Spawns gbrain as a subprocess against tempdir workspaces. Covers: scaffold
first-run + re-run no-op, reference diff + --apply-clean-hunks, migrate-fence,
scrub-legacy-fence-rows, harvest privacy-lint catch + --no-lint bypass, and
the install removed-error path. No DATABASE_URL needed — skillpack is
filesystem-only.

* chore: docs + VERSION + CHANGELOG for v0.36.0.0 (T13 + T14)

Skillpacks as scaffolding, not amber.

v0.36 retires the managed-block install model. Six new subcommands replace
install + uninstall: scaffold, reference (with --apply-clean-hunks), migrate-fence,
scrub-legacy-fence-rows, harvest, plus the existing list / diff / check
(check gains --strict for CI gating). Routing comes from each skill's
frontmatter triggers — gbrain does not touch your RESOLVER.md or AGENTS.md.

Companion editorial skill skillpack-harvest drives the genericization
checklist; default-on privacy linter catches Wintermute / email / Slack
references before they leak into gbrain core.

New docs guide at docs/guides/skillpacks-as-scaffolding.md walks the model
and the migration path for pre-v0.36 installs.

* fix(ci): privacy checks — allow-list harvest-lint tests, scrub user-facing fork-name references

CI's check-privacy.sh and check-test-real-names.sh both flagged the literal
fork name across the v0.36 skillpack diff. Two failure modes, two fixes:

1. **Meta-rule-enforcement files** added to both allow-lists. The harvest
   privacy linter's whole job is to catch the banned literal leaking into
   gbrain; its source has the regex pattern, its tests verify the linter
   fires by feeding it the banned string, and the skill markdown documents
   the substitution policy. Same exception status as check-privacy.sh and
   check-proposal-pii.sh themselves. Files allow-listed:
   - src/core/skillpack/harvest-lint.ts
   - test/skillpack-harvest-lint.test.ts
   - test/skillpack-harvest.test.ts
   - test/e2e/skillpack-flow.test.ts
   - skills/skillpack-harvest/SKILL.md

2. **User-facing references** swapped for canonical phrasing per CLAUDE.md's
   responsible-disclosure rule. README + new docs guide + 4 src docstrings
   + 1 test now say 'your OpenClaw' / 'host agent repo' / 'agentRepo' var
   name. Behavior unchanged — only documentation strings touched.

Verify gate (the script CI runs) passes locally: EXIT=0.
Tests still pass: 60/60 across the affected files.
llms-full.txt regenerated.

* fix(test): update check-resolvable-cli expectation for cwd_walk_up tier

Sister fix to the test/repo-root.test.ts update in commit a31418e3. The new
v0.33 cwd_walk_up tier fires before repo_root when running from inside the
gbrain repo — same skills/ dir matched, different source label. Behavior
unchanged; the legacy repo_root tier is now functionally subsumed (kept in
the type union for back-compat).

CI shard 3 failure: test/check-resolvable-cli.test.ts:171.

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

* fix(test): pin clock in sync_freshness boundary tests (CI flake)

The 24h and 72h exact-boundary tests scheduled last_sync_at relative to
Date.now() at construction time, then let the check call Date.now() again
internally. CI scheduler jitter between the two reads pushed ageMs past
the strict > thresholds by microseconds, dropping the 72h-boundary case
into the fail branch instead of warn.

Fix: add an optional `opts.now` test seam to checkSyncFreshness. The two
boundary tests now capture t0 once and pass it both to the timestamp
constructor and to the check, making ageMs deterministically equal to
the boundary. The non-boundary tests (4d, 30h, 2h, etc.) don't need
pinning — they're comfortably away from the > comparison.

CI shard 1 flake: test/doctor.test.ts:479. Locally 48/48 doctor tests pass.

* feat(skillpack): agent-onboarding readme + next-action hints on every CLI surface (DX review)

DX audit of the v0.36 scaffold model surfaced one structural gap and four
output gaps. When scaffolded files land on a downstream agent's disk, the
agent had no agent-facing manifest telling it what to do — no routing
contract, no upgrade flow, no two-way merge warning at the right surface.

Fixes:

1. **New shared dep: skills/_AGENT_README.md.** Lands on every scaffold +
   migrate-fence alongside the existing _brain-filing-rules.md and
   _output-rules.md. Short, agent-readable contract: walk *.SKILL.md
   frontmatter triggers: for routing, gbrain is reference not law on
   upgrade, no managed-block fence anymore, two-way merge has known
   limitations. Single source of truth for the agent operating contract.

2. **scaffold stdout** prints a next-action hint pointing at the readme
   (with absolute path) and the reference --all upgrade-sweep command.

3. **reference stdout** adds per-category decision policy:
   - missing → scaffold again
   - differs → was edit intentional? keep it. Accidental? patch by hand or
     apply-clean-hunks after reading the two-way warning.

4. **reference --apply-clean-hunks** prints the two-way merge WARNING
   BEFORE the apply (to stderr, survives stdout redirect). Spells out
   that gbrain has no scaffold-time base and local edits in differing
   sections WILL be aligned to gbrain. Skipped in --json mode for
   machine consumers. On conflicts, prints how to inspect and patch.

5. **migrate-fence stdout** tells the agent its routing model just
   changed (fence gone, walk frontmatter now) and points at
   scrub-legacy-fence-rows as the eventual cleanup. References the new
   _AGENT_README for fresh-install agents.

Smoke verified end-to-end: 16 files land (was 15, +1 for _AGENT_README),
hint prints with absolute path, readme lands on disk. Tests + verify gate
pass clean.

* feat(skillpack): upgrade-time reference sweep + reference --since version filter (DX deferred items)

Closes the last two DX gaps from the v0.36 audit:

1. **Post-upgrade reference sweep.** New `postUpgradeReferenceSweep`
   helper called at the end of `gbrain post-upgrade`. After migrations
   apply, auto-runs `reference --all` against the detected host
   workspace and prints a one-line-per-skill summary of drift. Five
   gates: GBRAIN_SKIP_REFERENCE_SWEEP env-var bypass, no detected
   workspace (silent), workspace IS gbrain repo (dev-mode silent),
   zero drift (silent), and pure-missing skills the host never
   scaffolded are filtered out as noise. All errors swallowed —
   never blocks post-upgrade. Helper accepts test-seam opts
   (gbrainRoot, targetWorkspace) for unit testability.

2. **`reference --all --since <version>`.** Filters the sweep to
   skills whose source actually changed in gbrain between
   <version> and HEAD, using a new `changedSlugsSinceVersion`
   helper in bundle.ts. Pure-JS git wrapper (spawnSync), no deps.
   Accepts bare '0.X.Y.Z' or 'v0.X.Y.Z' or commit SHA. Falls back
   loudly to full sweep when git can't resolve the ref (tarball
   install, missing tag).

Test coverage added — total +32 new test cases:

UNIT (15 cases):
- test/skillpack-changed-since-version.test.ts (9 cases): git-aware
  filter against a fixture git repo. Covers null on non-repo,
  null on bad tag, empty array on no changes, single + multi-slug
  drift (deduped + sorted), bare + v-prefix version forms, non-
  skills/ path filtering, SHA-prefix ref form.
- test/upgrade-reference-sweep.test.ts (6 cases): gate logic.
  Covers env-var bypass, zero drift, empty-host suppression,
  drift-detected output shape, dev-mode workspace==gbrain guard,
  error-swallowing contract.

E2E (8 new cases in test/e2e/skillpack-flow.test.ts):
- 10: scaffold lands skills/_AGENT_README.md
- 11: scaffold stdout prints the Next: hint
- 12: scaffold re-run (skipped-existing) suppresses the hint
- 13: reference stdout prints per-category decision policy
- 14: --apply-clean-hunks WARNING on stderr, not stdout
- 15: --apply-clean-hunks --json suppresses the WARNING (bug fix
  surfaced here: code originally printed unconditionally, now
  gated on !json)
- 16: migrate-fence stdout points at the new routing model
- 17: --since with a bad tag falls back to full sweep with warn

Local sweep: 579/579 pass across 18 affected test files, verify
gate EXIT=0, llms regenerated.

* docs(README): zero-base rewrite — 921 → 422 lines, refreshed catalog, MECE structure

The README had drifted into a changelog dumping ground. Four 'New in vX.Y'
paragraphs competed for the lead, 16 version tags scattered through
headings, the production-numbers hook (17,888 pages, 4,383 people) was
six months stale, and skills were described in three places (Skills section,
Commands section, inline marketing prose).

Zero-based rewrite:

**Refreshed catalog** (surveyed live brain + live agent fork, broad strokes
per CLAUDE.md privacy rules):
- ~100K total brain items (was 17,888 in the old README — 6x stale)
- ~16K people (was 4,383)
- ~5K companies (was 723)
- ~8K concepts, ~4K originals, ~3.5K daily notes
- ~31K media (30K tweets, 179 books, papers/films/games/interviews)
- 108 cron jobs running (was 21)
- 273 skills in the live agent fork (35 bundled + 238 user-built)

**Structure** — MECE, single source of truth per concept:
1. Hook + at-a-glance table (refreshed numbers)
2. Install (3 paths, terse)
3. What it does (5 capability areas — replaces 12 scattered sections)
4. Skills (categorized one-liners — 35 lines, was ~200)
5. How it works (one coherent flow — replaces 4 overlapping sections:
   Architecture, Knowledge Model, Knowledge Graph, Search, Why It Works)
6. Commands (terse cheatsheet — every command, one line each)
7. Docs (link map — points to docs/ for the heavy stuff)
8. Origin / Contributing / License

**Cut entirely** (moved or deleted):
- 4 'New in vX.Y' leads (→ CHANGELOG.md is the changelog)
- 16 (vX.Y) version tags in section headings
- Minions stats subsection (subsumed into hook + 'durable background work')
- Voice section (was 12 lines of brand prose)
- Engine Architecture detail (→ docs/architecture/)
- File Storage section (→ docs/guides/storage-tiering.md)
- Per-skill marketing prose (one-liner per skill in the table)

The README is no longer the changelog. Future releases append to
CHANGELOG.md; the README only changes when a structural capability does.

llms-full.txt regenerated. Privacy check + verify gate pass.

* docs(README): fix line-start '+' rendering bug + lead with eval evidence

Two fixes in one:

1. **Markdown bug fix.** The OAuth 2.1 paragraph had `+ PKCE,` on a line
   start (column 1), which GitHub-flavored markdown interprets as a list
   marker — the line break before it broke the paragraph and rendered as
   an orphan first line followed by a bullet. Rewrote the OAuth 2.1
   capabilities as inline-comma-separated, escaped the `+` semantics.
   Swept the whole file for the same bug class — no other instances.

2. **Maximum-sell mode for evals.** Surveyed every published benchmark
   in both this repo and ~/git/gbrain-evals. Strongest evidence pulled
   to the top:

   - **97.60% R@5 on the public LongMemEval _s (500 questions).** No LLM
     in the retrieval loop. $0.50 per 1000 queries. Beats MemPalace raw
     by a point on the same dataset, beats every academic dense
     retriever (Stella, Contriever, BM25). Mastra/Supermemory measure
     a different metric (QA accuracy with LLM judge) — flagged honestly.

   - **+31.4 points P@5 from the self-wiring knowledge graph** on
     BrainBench v0.20.0 (240-page rich-prose corpus, 145 relational
     gold queries). Separable, measured, load-bearing. Zero retrieval
     regression across seven releases (v0.16 → v0.20).

   New '## Benchmarks' section after Install:
   - Public benchmark table with cross-system comparison
   - In-house BrainBench scorecard with per-adapter Δ vs gbrain
   - Source-swamp resistance result (93.3% top-1 vs 80% grep-only)
   - Skill/prompt compression: 25KB → 13KB AGENTS.md, +13-17pp accuracy
     across Opus 4.7 / Sonnet 4.6 / Haiku 4.5
   - 'Run your own evals' subsection with copy-pasteable commands for
     every eval surface (longmemeval, cross-modal, eval capture/replay,
     BrainBench)

   Tightened the lead's cost-comparison claim to what's defensible per
   the underlying eval doc (MemPal LLM-rerank $0.001/q vs gbrain
   $0.0005/q; dropped the overstated '6x' I'd written initially).

Privacy + verify gate + build-llms test all pass.

* docs(README): integrate the eval story into the lead, move jargon into 'Receipts on the evals'

Previous lead dumped metric acronyms (R@5, P@5, P@5 deltas, MemPalace,
Stella, Contriever, BM25) before the reader knew what gbrain does. A
'somewhat technical' reader hits the wall of jargon and bounces.

Rewritten:

**Lead (jargon-free, 3 paragraphs)** — describes the value in plain
English, with two anchor numbers:
- 'right answer in top 5 results 97.6% of the time' (not 'R@5 97.60%')
- 'roughly 4x more relevant than plain vector RAG' (not '+31.4 pts P@5')
- 'better than every comparable system that doesn't pay for a language-
  model call on every retrieval' (the load-bearing honest framing,
  without naming the competitors mid-hook)
- ends with '[Receipts on the evals →]' linking down

**'## Benchmarks' renamed '## Receipts on the evals'** with a glossary
at the top defining R@5, P@5, and 'no LLM in the loop' in one line each.
Then the full tables: LongMemEval cross-system (with the metric-mismatch
flag for Mastra/Supermemory), in-house BrainBench scorecard, source-swamp
resistance, and prompt compression. The competitor names + metrics stay
here where readers who want the receipts can find them, with the
glossary so the acronyms don't tax cold readers.

Net: lead reads as 'here's what it does and the proof' instead of 'here
are the benchmark numbers, figure out what they mean.' Comparison facts
unchanged.

Privacy + verify gate + build-llms test all pass.

* docs(README): name LongMemEval explicitly + first-person voice in lead

Two specific edits from user feedback:

1. 'the standard public benchmark for AI memory systems' → 'LongMemEval'
   (linked to the HuggingFace dataset). The benchmark has a name; use it.

2. 'Built by the President and CEO of Y Combinator to run his own AI
   agents' (passive third-person) → 'I'm the President and CEO of Y
   Combinator, and I use this 16 hours a day' (active first-person).
   Carried the voice change through the rest of the README — the
   downstream 'Garry's personal agent' line and the Origin section's
   'Garry Tan needed... he'd ever drafted... so he built one' all flip
   to first person ('my personal agent', 'I needed', 'I'd ever drafted',
   'so I built one'). The README is now consistently first-person from
   the author's voice instead of a hagiographic third-person framing.

* docs(README): add Multi-player and company brains section

Three deployment patterns documented:

1. Single GBrain server + thin MCP clients (recommended). Tailscale
   private networking, OAuth scope, source-scoped clients, exhaustive
   what-clients-can/cannot-do lists.
2. Local PGLite + GStack for per-worktree code search.
3. Federated repos (advanced) — multiple servers indexing the same
   brain repo.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs(README): tighten install path + add tech-orientation block + visceral query example

Self-eval as a cold reader surfaced four gaps blocking a 10/10 first read:

1. Lead never says WHAT it is technically — CLI? service? cloud? local?
   Added a "What it is, technically" block right after the hook: open-source
   MIT, Bun CLI + MCP server, local-first, data stays on disk, MCP-native.
2. Install path optimized for committed users not evaluators. The old
   "recommended" path (deploy OpenClaw on Render, 8GB RAM) blocked anyone
   trying gbrain for the first time. Reordered into 3 paths by commitment:
   60-second standalone CLI first, MCP for Claude Code / Cursor second,
   full agentic install third.
3. No example output showing what success looks like. Added a real sample
   `gbrain query` invocation with the hybrid-search result format so a
   reader can feel the experience before they install.
4. Privacy / data-locality unaddressed in lead. Now stated up front:
   embedding calls only hit external APIs if you configure them.

## [0.36.0.0] - 2026-05-17
**Skillpacks are scaffolding now, not amber. Scaffold once, own the files, fork freely.**
GBrain v0.36 retires the managed-block install model. `gbrain skillpack install` and `uninstall` are gone — replaced by `scaffold` (one-time additive copy), `reference` (read-only diff lens against gbrain's bundle), `migrate-fence` (one-shot transition from the old fence), `scrub-legacy-fence-rows` (opt-in row cleanup), and `harvest` (lift a proven skill from a host repo back into gbrain). The whole "amber" surface — managed block, cumulative-slugs receipt, content-hash gates, lockfile, prune semantics — is deleted. ~600 LOC of mechanism comes out; ~400 LOC of new modules + ~1000 LOC of new test coverage replace it. The point is that scaffolded skills are first-class members of your agent repo. You own them. gbrain becomes a reference library, not a package manager.
### What you can now do
**Scaffold a skill into your real agent repo and own it outright.** `cd ~/git/wintermute && gbrain skillpack scaffold book-mirror` copies the skill markdown, any sibling routing-eval fixtures, and any paired source files declared in the skill's frontmatter `sources:` array. No managed-block fence written to your `RESOLVER.md`. No `cumulative-slugs` receipt. No `.gbrain-skillpack.lock` file. The files are yours. Edit freely; re-scaffolding refuses to overwrite anything that exists.
**Read the diff against gbrain's bundle as reference, not as a force-update.** `gbrain skillpack reference book-mirror` prints per-file status (`identical` / `differs` / `missing`) plus unified diffs for any drift, framed with an agent-readable header: "These files live at <path> as reference. Read them and decide what (if anything) to integrate into your local skills/. Your local edits are intentional — do not blindly overwrite." For a one-line-per-skill sweep, `reference --all`. For two-way auto-apply of non-conflicting hunks, `reference <name> --apply-clean-hunks` (with a documented two-way merge limitation — no scaffold-time base tracking, by design).
**Migrate off the old managed block with one command.** `gbrain skillpack migrate-fence` strips `<!-- gbrain:skillpack:begin -->` / `end -->` markers and the manifest receipt comment from your resolver file, preserving every row inside the fence verbatim as user-owned routing. Cumulative-slugs receipt missing or stale → falls back to row-parsing with a loud warning. Idempotent; re-runs are no-ops. Once your agent confirms it walks frontmatter `triggers:` for routing, `gbrain skillpack scrub-legacy-fence-rows` tears down the bridge — removes legacy rows whose skill exists AND declares non-empty triggers, preserves anything user-added.
**Lift a proven skill back into gbrain so other clients can scaffold it.** `gbrain skillpack harvest my-skill --from ~/git/wintermute` is the inverse loop. Reads the host skill's `skills/<slug>/` + any paired source files, copies into gbrain's tree, updates `openclaw.plugin.json` (sorted), and runs a default-on privacy linter against `~/.gbrain/harvest-private-patterns.txt` (built-in defaults catch `\bWintermute\b`, common email regex, Slack channel patterns). Any match → rollback (delete the copy) and exit non-zero so the editorial pass surfaces the leak. Symlinks in the host skill dir are rejected; canonical-path containment prevents path traversal. The companion editorial skill `skillpack-harvest` walks the genericization checklist (scrub fork names, generalize triggers, lift fork-specific conventions to references).
**Gate CI on bundle drift without breaking interactive use.** `gbrain skillpack check` defaults to informational (exit 0 even with drift) when invoked as a subcommand. Pass `--strict` to opt into exit-1 on action-needed for CI gating. Top-level `gbrain skillpack-check` (the cron entry point) keeps its existing exit-1 behavior for backwards compat.
**Auto-detect a target workspace in non-OpenClaw repos.** `autoDetectSkillsDir` gains a `cwd_walk_up` tier ahead of the `~/.openclaw/workspace` fallback. `cd ~/git/wintermute && gbrain skillpack scaffold ...` finds wintermute automatically. `$OPENCLAW_WORKSPACE` precedence preserved when explicitly set — the precedence regression (R5) is pinned by a test.
### Migration
Existing pre-v0.36 installs:
```bash
gbrain skillpack migrate-fence # one-shot, strips the fence
# (after confirming your agent walks frontmatter)
gbrain skillpack scrub-legacy-fence-rows
```
Scripts referencing `gbrain skillpack install` or `gbrain skillpack uninstall` will exit non-zero with a hint pointing at the replacement command. There's no deprecated alias — this is a clean break. Update the scripts once and move on. The bundled skill markdown + paired source files are yours to edit; cleanup is `rm -rf skills/<slug>/` (consult the skill's frontmatter `sources:` for any paired files to remove alongside).
### For contributors
Major file/test surface changes:
- New: `src/core/skillpack/{copy,scaffold,reference,migrate-fence,scrub-legacy,harvest,harvest-lint,apply-hunks,diff-text}.ts`

Codex HIGH-1 fix applied: trust narrowing happens at the tool-allowlist layer (subagents can't call put_page) instead of allowedSlugPrefixes — untrusted EPUB content cannot prompt-inject any people page. Cost-estimate prompt before launching; refuses to spend in non-TTY without `--yes`. Per-chapter idempotency keys (`book-mirror:<slug>:ch-<N>`) for retry-friendly re-runs.

Never clobbers local edits; tracks a skill manifest so subsequent `install --update` diffs cleanly. Bundle builder (`skillpack/bundle.ts`) packages the set from `skills/` into a versioned payload. **v0.24.0:** managed block embeds a `<!-- gbrain:skillpack:manifest cumulative-slugs="..." version="..." -->` receipt inside the fence. Per-skill installs accumulate via `union(prior_receipt, this_call)`; `install --all` is the only path that prunes (drops slugs no longer in the bundle). Rows inside the fence whose slug is in neither the new cumulative set nor the bundle survive as user-added with a stderr `[skillpack] unknown row in managed block: "<slug>" — Investigate: ...` warning. Pre-v0.24 fences upgrade silently on first install (extracted slugs become the prior cumulative set). **v0.25.1:** `gbrain skillpack uninstall <name>` lands as a real CLI subcommand. Inverse of install with symmetric data-loss posture: D8 refuses if the slug isn't in the cumulative-slugs receipt (won't nuke a hand-added row); D11 content-hash guard refuses if any installed file diverges from the bundle (you've edited it locally) unless `--overwrite-local` is passed. `applyUninstall` enforces an atomic-refusal contract: pre-scans ALL files for divergence; refuses BEFORE any unlink fires if anything is blocked. The bug fix landed via `test/skillpack-uninstall.test.ts`'s D11 case — the test was written with the contract in mind, the original implementation interleaved hash-check + unlink, and the lie surfaced immediately.

New surface: `scaffold` (one-time additive copy via shared `copyArtifacts` helper in `copy.ts`; refuses to overwrite existing files; partial-state fills missing paired sources declared in SKILL.md frontmatter `sources:`), `reference` (read-only diff lens with agent-readable framing line + `--apply-clean-hunks` two-way auto-apply via pure-JS unified-diff parser/applier in `apply-hunks.ts` + `diff-text.ts`), `migrate-fence` (one-shot strip of legacy fence; cumulative-slugs receipt → row-parsing fallback; preserves rows verbatim as user-owned routing), `scrub-legacy-fence-rows` (opt-in row cleanup with skill-present + non-empty-triggers gate), `harvest` (host→gbrain inverse with symlink-reject + canonical-path containment via `validateUploadPath`-style gate + default-on privacy linter in `harvest-lint.ts` against `~/.gbrain/harvest-private-patterns.txt` plus built-in `\bWintermute\b` + email + Slack-channel patterns; rollback on match).

Replaced wholesale in v0.36.
- `src/core/archive-crawler-config.ts` (v0.25.1) — D12 + codex HIGH-4 safety gate for the `archive-crawler` skill. Refuses to run unless `archive-crawler.scan_paths:` is explicitly set in the brain repo's `gbrain.yml`. Mirrors the storage-config.ts parsing pattern (sibling file; separate concern from storage tiering). `loadArchiveCrawlerConfig(repoPath)` throws `ArchiveCrawlerConfigError(missing_section | empty_scan_paths | invalid_path | parse_error)`. `normalizeAndValidateArchiveCrawlerConfig` rejects relative paths and `..` traversal; `~` is expanded; trailing-slash normalized for unambiguous prefix matching. `isPathAllowed(candidate, config)` is the runtime per-file gate (scan_paths prefix-match with directory-boundary correctness; deny_paths overrides). Tests in `test/archive-crawler-config.test.ts` (19 cases).
- `test/helpers/cli-pty-runner.ts` (v0.25.1) — generic real-PTY harness ported from gstack and trimmed to ~470 lines. Uses pure `Bun.spawn({terminal:})` (Bun 1.3.10+; engines.bun pin in package.json). Generic primitives only — no plan-mode orchestrators. Exports: `launchPty`, `resolveBinary`, `stripAnsi`, `parseNumberedOptions`, `optionsSignature`, `isNumberedOptionListVisible`, `isTrustDialogVisible`. Self-tests in `test/cli-pty-runner.test.ts` (24 cases).
- `src/core/skill-manifest.ts` (v0.19) — parser for `skill-manifest.json` records. Used by skillpack installer to detect drift between the shipped bundle and the user's local edits, so updates merge instead of overwriting.

# Skillpacks as scaffolding, not amber
GBrain v0.33 reshapes `gbrain skillpack` from a package manager into a
scaffold + reference library. This guide explains the model and the
workflow.
## Why we changed it
Pre-v0.33 (the "amber" model):
- `gbrain skillpack install <name>` copied bundled skills into your
workspace AND wrote a managed-block fence into your `RESOLVER.md` /
`AGENTS.md` with a `cumulative-slugs="..."` receipt.
- Subsequent installs hash-checked every file and refused to overwrite
local edits unless you passed `--overwrite-local`.
- `gbrain skillpack uninstall` had its own data-loss safeguards (D8
receipt gate + D11 content-hash pre-scan) and rebuilt the fence.
It worked, but it treated personal-AI skills like vendor packages.
Users couldn't cleanly fork a skill without the next install fighting
them. Every release re-litigated the same managed block. The test
surface alone for the managed block was ~1000 lines.
Skills aren't vendor packages. They're first-class code in your agent
repo. You scaffold once, you own them, you fork and edit freely. When
gbrain ships a new version, you ask "what changed?" — the agent reads
the diff and decides what (if anything) to integrate.
## The five commands
### `gbrain skillpack scaffold <name> [--workspace PATH]`
One-time, additive copy of a bundled skill into your repo. Refuses to
overwrite any file that exists. Routing comes from each skill's
frontmatter `triggers:` array — gbrain does NOT touch your `RESOLVER.md`
or `AGENTS.md` (see "How agents discover scaffolded skills" below).
```bash
cd ~/git/your-agent-repo
gbrain skillpack scaffold book-mirror
# files in skills/book-mirror/ + (if the skill declares paired source)
# src/commands/book-mirror.ts land in your workspace
```
`scaffold --all` copies every bundled skill that's missing. Never
prunes.
If a skill's frontmatter declares paired source files (`sources: [...]`
in the SKILL.md YAML head), scaffold copies them too. The partial-state
policy handles "skill shipped earlier, gained a paired source later" —
scaffold copies the new paired file even when the skill dir already
exists.
### `gbrain skillpack reference <name> [--workspace PATH] [--apply-clean-hunks] [--json]`
Read-only update lens. Diffs gbrain's bundle against your local copy
and emits per-file status (`identical` / `differs` / `missing`) plus
unified diffs for any `differs` entries.
```bash
gbrain skillpack reference book-mirror
# These files live at <gbrain-path> as reference. Read them and
# decide what (if anything) to integrate into your local skills/.
# Your local edits are intentional — do not blindly overwrite.
#
# reference: identical:14 differs:1 missing:0
#
# differs /your/workspace/skills/book-mirror/SKILL.md
# --- a/skills/book-mirror/SKILL.md
# +++ b/skills/book-mirror/SKILL.md
# @@ -10,3 +10,5 @@
# ... unified diff ...
```
`reference --all` sweeps the whole bundle (one-line-per-skill summary).
`reference <name> --apply-clean-hunks` is the auto-apply path. It
parses the diff between gbrain's bundle and your local copy, applies
every hunk whose pre-change context matches uniquely. **Two-way merge
limitation**: without scaffold-time base tracking (intentionally
out-of-scope for v0.33), this cannot distinguish "gbrain changed X"
from "you changed X." Applied hunks align everything to gbrain. Use
`--dry-run` first to preview, or run plain `reference` to inspect the
diff before letting auto-apply touch anything.
### `gbrain skillpack migrate-fence [--workspace PATH] [--dry-run]`
One-shot conversion for workspaces on the pre-v0.33 managed-block
model. Strips the `<!-- gbrain:skillpack:begin -->` / `end -->`
markers and the manifest receipt comment from your resolver file.
**Preserves every row inside the fence verbatim.** Those rows become
user-owned routing the agent can still see during the transition to
frontmatter-based discovery.
```bash
cd ~/git/your-agent-repo
gbrain skillpack migrate-fence
# migrate-fence: fence_stripped
# resolver: /your/workspace/skills/RESOLVER.md
# fenced slugs: alpha, beta, gamma
# already present: alpha, beta
# skills copied: gamma (additive — beta and alpha kept their local edits)
```
Idempotent. Re-running after migration finds no fence and exits 0.
### `gbrain skillpack scrub-legacy-fence-rows [--workspace PATH] [--dry-run]`
Opt-in cleanup. Once you've confirmed your agent walks frontmatter
`triggers:` for routing, this command removes the legacy rows that
`migrate-fence` left behind.
**Two-condition gate** (both must hold for a row to be removed):
1. `skills/<slug>/` exists on host (it was a real scaffold).
2. That skill's frontmatter declares non-empty `triggers:` (proof
that frontmatter discovery covers this skill).
Rows whose slug fails either gate are preserved — user-owned routing
the migration shouldn't touch.
### `gbrain skillpack harvest <slug> --from <host-repo-root> [--no-lint] [--dry-run]`
Inverse of scaffold: lifts a proven skill from your host repo back
into gbrain so other clients can scaffold it. Default behavior:
- Symlinks in the host skill dir are rejected (canonical-path
confinement).
- Privacy linter scans the harvested files against
`~/.gbrain/harvest-private-patterns.txt` plus built-in defaults
(canonical private fork name, common email regex, Slack channel pattern). Any
match → rollback (delete the harvested files) and exit non-zero.
- `openclaw.plugin.json` updated with the new slug, sorted.
- `--no-lint` bypasses the linter (after a manual editorial scrub).
Use the `skillpack-harvest` skill (its companion editorial workflow)
to walk the genericization checklist before running the CLI.
## How agents discover scaffolded skills
Routing under the new model lives entirely in each skill's frontmatter:
```yaml
---
name: book-mirror
triggers:
- "personalized version of this book"
- "mirror this book"
- "two-column book analysis"
---
```
Your agent's job at runtime is to walk `skills/*/SKILL.md`, parse the
frontmatter, and match the user's intent against every skill's
`triggers:` array. When a match scores high enough, invoke that skill.
This replaces the v0.32 model where `gbrain skillpack install` wrote
table rows into your `RESOLVER.md`. Rows are gone (or, for users
migrating from the old model, preserved transitionally by
`migrate-fence` until they run `scrub-legacy-fence-rows`).
If you're a downstream agent author updating to this model:
1. On startup, scan `skills/*/SKILL.md` for frontmatter.
2. Build an in-memory routing table from each skill's `triggers:`
array.
3. On every user message, match against this table — either by
substring containment, semantic similarity, or whatever your
downstream agent already does for intent classification.
## Removing a scaffolded skill
There's no `gbrain skillpack uninstall` command in v0.33. The files
in your `skills/<slug>/` are first-class members of your repo —
delete them like any other code:
```bash
rm -rf skills/book-mirror
# if the skill declared paired source files:
rm src/commands/book-mirror.ts
# (consult the skill's frontmatter `sources:` array for the full list)
# if no other scaffolded skill needs them, you can also remove the
# shared deps that scaffold drops in:
rm skills/_brain-filing-rules.md
rm -rf skills/conventions/
rm skills/_output-rules.md
```
You own the files. There's no manifest to update, no fence to rebuild.
## When to use which command (quick decision tree)
- **New host repo, want a gbrain skill** → `scaffold`
- **gbrain shipped a new version, want to see what's changed**
→ `reference` (read-only) or `reference --apply-clean-hunks` (auto)
- **Upgrading from v0.32 or earlier** → `migrate-fence` (one-shot)
- **Cleanup after `migrate-fence`** → `scrub-legacy-fence-rows`
- **Lift your fork's skill back into gbrain** → `harvest` + the
`skillpack-harvest` editorial skill
## What about `install` and `uninstall`?
Both are removed in v0.33. Running either prints an error pointing at
the replacement command. No deprecated alias — this is a clean break.
If you have existing scripts referencing the old names, update them
once and move on.

# Agent onboarding — what to do with the files in this directory
You (the agent) are running on a host that scaffolded gbrain skills here. This
file is the operating contract. Read it on every cold start. It is short on
purpose.
## What lives in this directory
```
skills/
_AGENT_README.md ← you are here
_brain-filing-rules.md ← where to file brain pages (read on every write)
_output-rules.md ← output quality standards (no LLM slop, exact phrasing)
_friction-protocol.md ← log friction the user hits to ~/.gstack/friction/
conventions/ ← cross-cutting rules every skill defers to
<skill-name>/
SKILL.md ← the skill's contract + workflow
routing-eval.jsonl ← (optional) test fixtures for routing-eval
script.ts ← (optional) deterministic code, if any
```
Other files in the host repo's `src/`, `docs/`, `recipes/` etc. are owned by the
host, not by gbrain. Don't treat them as gbrain artifacts.
## Routing — your first job
Discover skills at runtime by walking every `skills/<slug>/SKILL.md` here and
parsing the YAML frontmatter. Each skill declares one or more `triggers:`
strings; they are the user-facing phrases that route to that skill.
```yaml
---
name: book-mirror
triggers:
- "personalized version of this book"
- "mirror this book"
- "two-column book analysis"
---
```
On every user message, match the message against every skill's `triggers:`
array. Substring match is the baseline. Semantic similarity (embedding or
keyword expansion) is fine on top. When a trigger matches strongly, invoke the
skill — read its SKILL.md body in full and follow the workflow described there.
**Do NOT** look for a managed-block table inside `RESOLVER.md` or `AGENTS.md`.
That pattern was retired in gbrain v0.36. Routing lives in frontmatter now.
## When the user invokes a skill
Read the entire `skills/<slug>/SKILL.md` file. Follow its `## Phases`,
`## Workflow`, or equivalent step-by-step section. If the skill has a
`mutating: true` frontmatter and declares `writes_pages:` / `writes_to:`,
those are the brain-side write surfaces — consult `_brain-filing-rules.md`
to confirm the file path is sanctioned.
If the SKILL.md frontmatter declares `sources:` (paired source files), those
live at their mirror path in the host repo (e.g. `src/commands/<slug>.ts`).
They are reference code that the gbrain CLI calls. You do not run them
directly unless the SKILL.md tells you to.
## Updates — when gbrain ships a new version
The user runs `gbrain upgrade`. Skill files DO NOT change automatically.
gbrain becomes a reference library you compare against.
On every cold start, or any time the user mentions an upgrade, run:
```bash
gbrain skillpack reference --all
```
That sweeps every bundled skill and reports per-skill `identical / differs /
missing` counts. For each `differs`:
```bash
gbrain skillpack reference <slug>
```
This prints a unified diff between gbrain's bundle and the local file. Read
it, then decide per file:
- **Local edit was intentional.** Keep your version. gbrain is reference, not
law.
- **Local edit was accidental drift** (e.g. you wrote stale content into the
skill body). Either patch by hand, or run
`gbrain skillpack reference <slug> --apply-clean-hunks` (read the WARNING
about two-way merge below first).
- **Genuinely new gbrain change in a section you don't care about.** Skip or
apply per your judgment.
For `missing` files (gbrain added a new bundled skill since you scaffolded),
run `gbrain skillpack scaffold <new-slug>` to bring it in.
### `reference --apply-clean-hunks` — two-way merge warning
This command does a two-way diff against gbrain's current bundle. It does
NOT have access to the version you originally scaffolded. Consequence: if
the user's local file differs from gbrain in ANY section (including
intentional user edits), those sections WILL be aligned to gbrain.
Always run plain `gbrain skillpack reference <slug>` first to inspect.
Use `--apply-clean-hunks` only when you're confident the local edits were
accidental or you want to fully reset to gbrain's current bundle.
## Removing a scaffolded skill
There is no `uninstall` command in v0.36. The files are yours.
```bash
rm -rf skills/<slug>
# if the skill declared paired source files:
rm src/commands/<slug>.ts
```
Consult the skill's frontmatter `sources:` array for the full paired-file
list before deleting.
## When in doubt
The single source of truth for the model is
`docs/guides/skillpacks-as-scaffolding.md` in the gbrain repo. The skill
files you scaffolded are the source of truth for individual skill behavior.
This file (`_AGENT_README.md`) is the routing contract — keep it short.

This skill is the inverse of `gbrain skillpack scaffold`. Scaffold ships
skills downstream (gbrain → host). Harvest lifts proven patterns
upstream (host → gbrain) so they become references every other client
can scaffold.
## Contract
A harvest is "properly done" when:
1. The host skill is mature (used in production, recent routing-eval
cases pass).
2. The editorial genericization in Phase 3 has scrubbed every
fork-specific reference (names, real entities, internal channels).
3. `gbrain skillpack harvest --dry-run` previewed the file set.
4. The real `gbrain skillpack harvest <slug> --from <host>` succeeded
with `status: harvested` (no privacy-lint hits).
5. `bun test test/skills-conformance.test.ts` passes on the new
`skills/<slug>/SKILL.md`.
6. The user has reviewed the diff in gbrain and explicitly approved
the commit.
If any of these is incomplete, the skill is NOT yet harvested — the
files may sit in gbrain's working tree, but they're not landed.
## Output Format
This skill produces three artifacts in gbrain's working tree:
1. `skills/<harvested-slug>/SKILL.md` (and any sibling files like
`routing-eval.jsonl`)
2. Paired source files at their mirror paths (e.g.
`src/commands/<slug>.ts`) when the host SKILL.md declared them
in frontmatter `sources:`
3. An updated `openclaw.plugin.json` with the new slug added to
`skills:` (sorted)
The session output to the user is a one-line success summary plus
a list of files written. JSON mode (`--json`) returns the full
`HarvestResult` shape for machine consumption.
## Anti-Patterns
- **Skipping the dry-run.** Always preview first. Files land in
gbrain's working tree; cleanup is a `git checkout` away, but you
shouldn't need to.
- **Trusting the linter alone.** The default regex set catches the
common cases. It doesn't catch every proper noun. Phase 3 (the
editorial pass) is the primary defense.
- **Harvesting `--no-lint` without justification.** The lint exists
for a reason. If you bypass it, document why in the commit.
- **Harvesting a skill that's still in flux.** Wait until the host
version stabilizes. Otherwise you'll harvest, then re-harvest,
then re-harvest, and that churns gbrain's bundle for no benefit.
- **Moving files instead of copying.** Harvest is a copy. The host
retains its skill. Don't `rm -rf` the source after harvesting.
- **Harvesting batch (multiple skills at once).** Not supported, and
for good reason — the editorial review per skill is real work.
## When to invoke
- The user developed a skill in their host fork (Wintermute, Neuromancer,
Zion, etc.) and wants other gbrain clients to be able to use it
- A skill has proven itself in production and is ready to generalize
- The user explicitly asks to "harvest" or "publish" a skill upstream
Do NOT invoke when:
- The skill is still in flux locally — let it stabilize first
- The skill references private content that can't be generalized
- The user just wants to share a one-off draft (use a gist instead)
## Preconditions
Before running this skill, confirm:
1. **The skill is mature.** Recent `routing-eval.jsonl` cases pass; the
skill has been used in production at least a few times.
2. **The skill is generalizable.** Strip-test in your head: replace
every fork-specific name. Does it still make sense as a skill?
3. **The user owns the gbrain checkout.** The harvest writes into
gbrain's working tree. They'll review and commit. Don't harvest
into a checkout the user doesn't intend to commit from.
## Workflow
### Phase 1 — Plan
Ask the user:
- What slug should the harvested skill have? (Slugs must be kebab-case,
globally unique in the gbrain bundle.)
- Which host repo is the source? (Path to repo root, not to the skill
directory — e.g. `~/git/wintermute`, not `~/git/wintermute/skills/foo`.)
- Should paired source files come along? (Check the host SKILL.md's
frontmatter `sources:` array.)
### Phase 2 — Dry-run + privacy-lint preview
Run the CLI with `--dry-run`:
```bash
gbrain skillpack harvest <slug> --from <host-repo-root> --dry-run
```
The output shows:
- Which files would land in gbrain's tree
- Whether paired sources are included
- (Implicit) The skill's frontmatter triggers — read them and check
they generalize
Do **not** skip the dry-run. The privacy linter only runs on a real
harvest, but the dry-run preview lets you see the files before they
land. Spot-check the SKILL.md and any paired source for things the
linter might miss (proper nouns, internal project names, etc.).
### Phase 3 — Genericization checklist (the editorial pass)
Before running the real harvest, walk the host's `skills/<slug>/`
files and apply this checklist. If anything matches, edit the host
file FIRST, then run harvest.
1. **Fork-specific names → generic phrasing**
- `Wintermute` → `your OpenClaw` (or `OpenClaw deployment`)
- `Neuromancer`, `Zion`, `<personal-fork-name>` → same treatment
- Personal first names (`garry`, `jane`, etc.) → `the user` /
`you` / a generic placeholder
2. **Real entities → placeholders**
- Real people, companies, deals, funds → placeholder slugs
(`alice-example`, `acme-example`, `fund-a`, etc.)
- Email addresses → strip entirely OR use `example@example.com`
- Internal Slack channels → `#some-channel` or strip
- Specific tracker IDs / Linear ticket numbers → strip
3. **Fork-specific conventions → references**
- Mentions of `<host-repo>/docs/...` files → either lift the doc
into gbrain OR replace with a generic placeholder explanation
- Mentions of `<host-repo>/skills/<other-fork-only-skill>` → either
decide to harvest that one too, or replace with a generic
pattern reference
4. **Triggers array generalizes**
- Read every entry in frontmatter `triggers:`. None should
reference the user's name, fork name, or internal tools.
- "Have garry sign off on it" → "have the user sign off on it"
5. **routing-eval.jsonl examples are scrubbed**
- Open `skills/<slug>/routing-eval.jsonl`. Every `intent` field
gets the same scrub as `triggers:`.
6. **Code comments + log strings**
- If a paired source is going to be harvested, walk it for the
same private-pattern leaks. Comments are the most common
hiding spot.
### Phase 4 — Real harvest
Once Phase 3 is complete, run the real harvest:
```bash
gbrain skillpack harvest <slug> --from <host-repo-root>
```
Default behavior:
- Path-confinement + symlink rejection at file copy
- Privacy linter runs against `~/.gbrain/harvest-private-patterns.txt`
(plus built-in defaults: `\bWintermute\b`, email, Slack channels)
- On any match → rollback (delete the harvested files) + exit non-zero
- `openclaw.plugin.json` updated to add the slug, sorted
Outcomes:
- `harvested` — success, manifest updated, files in gbrain's tree
- `lint_failed` — privacy linter caught something. Go back to Phase 3,
scrub the host file, retry.
- `slug_collision` — gbrain already has a skill at that slug. Either
use a different slug, or pass `--overwrite-local` if you really
mean to replace.
### Phase 5 — Verify in gbrain
After a successful harvest:
1. `bun test test/skills-conformance.test.ts` — confirms the new
SKILL.md meets the frontmatter contract.
2. `gbrain skillpack check --strict` — confirms no drift between
bundle and gbrain's own checkout.
3. `gbrain skillpack list` — confirms the slug shows up in the bundle.
4. Review the diff: `cd <gbrainRoot> && git diff -- skills/<slug>/`
5. Commit the additions in gbrain (do NOT commit any leftover files
in the host repo — harvest is a copy, not a move).
### Phase 6 — Downstream announcement (optional)
If other gbrain clients should pick up the new skill:
- Note it in `CHANGELOG.md` under "Skills added" for the next release
- Tag the user / contributor in the PR if the skill came from
someone outside the core team
## Bypass: `--no-lint`
The privacy linter is the safety net. The editorial pass is the
primary defense. If you've completed Phase 3 thoroughly and the
linter is still firing on a false positive, use `--no-lint`:
```bash
gbrain skillpack harvest <slug> --from <host-repo-root> --no-lint
```
**Document the bypass in the commit message.** Future maintainers
should be able to see WHY the lint was bypassed (e.g. "Wintermute
appears in a citation, not a real reference — verified manually").
Never bypass the linter on a casual basis. The whole point of the
default-on lint is that real names occasionally slip through the
editorial pass.
## What harvest does NOT do
- It does NOT move files (it copies). The host's `skills/<slug>/`
stays in place.
- It does NOT auto-scrub names. The editorial pass is human-driven.
- It does NOT publish to npm or a remote bundle. It writes to
gbrain's working tree; the user commits + ships via the normal
gbrain release process.
- It does NOT support `--all` (no batch harvest). One skill at a
time keeps the editorial review tractable.
## Files this skill touches
- gbrain's `skills/<slug>/` — every file in the host skill dir
(copy)
- gbrain's mirror path for declared paired sources
(e.g. `src/commands/<slug>.ts` if the host SKILL.md declares it
in frontmatter)
- gbrain's `openclaw.plugin.json` — adds the slug to `skills:`
array, sorted alphabetically

* and decide.
* 3. **Partial-state policy.** When `skills/<slug>/` already exists

/**
* Tests for `postUpgradeReferenceSweep` in src/commands/upgrade.ts —
* the v0.36 hook that prints a one-line-per-skill summary of drift
* after `gbrain upgrade` so an operator/agent doesn't have to manually
* run `gbrain skillpack reference --all`.
*
* Pins:
* - GBRAIN_SKIP_REFERENCE_SWEEP=1 short-circuits silently
* - no detected workspace → silent no-op
* - workspace == gbrain repo (dev mode) → silent no-op
* - zero drift (everything identical or never-scaffolded) → silent
* - drift detected → prints header + per-skill summary + footer hints
* - non-scaffolded skills (pure missing) suppressed from the summary
*
* The function is exported from upgrade.ts so we can drive it without
* spawning a full `gbrain upgrade` subprocess. We swap the cwd via
* process.chdir() to control what autoDetectSkillsDirReadOnly returns.
