| description | A read-only integrity health check for forge — a deterministic script (forge-doctor.sh/.js) surveys the .forge/ state contract and docs/manifests and reports inconsistencies with severity + fix hints, exiting 0/1/2 so it doubles as an AI-free CI gate. Catches orphaned/broken state, half-sealed done/, an un-integrated branch root, version drift, README bilingual drift, ADR-ID issues, missing script twins. Writes nothing, never auto-fixes (fg-status: where am I; fg-doctor: is the state healthy). Use in contexts like 'forge doctor', '무결성 검사', '상태 점검', 'health check', 'check forge state'. |
fg-doctor — state & docs integrity health check (outside the loop)
This is not a stage of the forge loop. It is an on-demand, read-only utility (like fg-status / fg-map) that answers a different question than fg-status: fg-status reports "where am I" (progress + the next step), fg-doctor reports "is the state healthy" (integrity violations). It is forge's answer to the harness-engineering init.sh health check (ADR-0019) — forge's state contract is hand-edited Markdown, so it can silently break, and nothing else actively verifies it.
It writes nothing and never auto-fixes — it surveys, classifies each finding by severity, and prints an actionable fix hint per finding. The actual fix is the human's to make (via fg-quick / fg-ask). It never auto-runs — no other skill invokes it; you run it on demand.
Language: This skill file is authored in English, but you MUST write every message shown to the user — the relayed report, and the closing line — in the user's language (detect it from the user's own messages), never mirroring this file's English. The script's finding tokens are language-neutral; render the report in the user's language.
How it runs (script-backed survey — ADR-0020 / ADR-0022)
The mechanical survey — walking the .forge/ state contract and the docs/manifests, classifying each finding, computing the severity — is done by a deterministic script, not by an LLM re-reading everything and hand-reasoning each check in tokens (that was slow and drift-prone; the same problem ADR-0020 fixed for fg-status). This skill runs the script and relays its report in the user's language; it does not re-survey.
The script exists so the check also works AI-free as a CI gate (see "CI usage"): a pipeline runs forge-doctor.sh and fails the build on a non-zero exit. Like fg-status's survey it is read-only — it mutates nothing (fg-doctor's contract, ADR-0019). Guarded by scripts/forge-doctor.test.sh + scripts/forge-doctor.parity.test.sh.
Dual dispatch (ADR-0022): prefer bash, fall back to node.
- Has bash:
bash "${CLAUDE_PLUGIN_ROOT}/scripts/forge-doctor.sh"
- No bash (e.g. PowerShell-blocked Windows):
node "${CLAUDE_PLUGIN_ROOT}/scripts/forge-doctor.js" — identical findings/severity/exit (guarded by the parity test).
Output: one [severity] check — path\n fix: hint line per finding, then a verdict line 🩺 forge-doctor — N errors, M warnings, K info. Exit code: 0 clean · 1 warnings only · 2 one or more errors.
Route on the exit code / relay:
- exit 0 → relay the clean bill of health in one line (do not manufacture findings).
- exit 1 / 2 → relay the findings grouped by severity, each with its path and fix hint, in the user's language. Then state that fg-doctor changed nothing and that fixes are the human's to make — trivial ones via fg-quick, larger ones via fg-ask. Do not auto-fix or auto-invoke either (the same read-only restraint as fg-status).
What the script checks (its contract — keep in sync if the script changes, per ADR-0020)
The two sections below document the script's checks so the contract is legible; the script is the source of truth for how they run. It resolves the forge root per FORGE-ROOT.md (ADR-0011) and applies it per group (Group A = the resolved branch root; Group B ADR check = the read overlay across top-level + branch root; other Group B = repo-root files). It ignores .forge/dropped/ (fg-drop's archive — out of the active contract, ADR-0021) and accepts both STATUS field forms (field: and the legacy - field:).
Group A — state-contract integrity (.forge/):
- A1 active-slot orphan — a
run.md/STATUS.md with no plan.md — error.
- A2 STATUS field validity —
status ∈ {executed, done}; verified ∈ {yes/skipped/n/a/pending/failed}; retro pending/skipped/path. Missing/invalid — error (active/executed), warning (legacy done may lack verified:).
- A3 slug pairing & retro consistency — plan
forge-slug == STATUS slug; a retro: path must point to an existing file (dangling — error); a done/ reading retro: pending — warning.
- A4 half-sealed done/ — every
done/*/STATUS.md reads status: done; else — error.
- A5 executed/ consistency — each
executed/<slug>/ has plan+run+STATUS at status: executed; else — warning.
- A6 backlog markers & task-number uniqueness — each backlog plan has
forge-slug+task:; a duplicate task: across all plans — error (missing marker — warning).
- A7 stale ask.md —
ask.md older than 1 day — warning.
- A8 orphaned branch root (NEW) — a
.forge/branch/<other>/ leaf root present on this branch — warning, hint: "did you forget fg-merge <branch> after the git merge?" This is the team safety net for the "merged but never integrated" silent data-loss gap.
Group B — docs & manifest integrity (repo root / ADR overlay):
- B8 manifest version sync (3 places) — error. B9 manifest JSON validity — error. B10 skill
name: frontmatter — error. B12 CLAUDE.md skill-list completeness — warning. B13 README bilingual skill-row parity — warning. B15 script twin parity (.sh↔.js, excluding *.test.sh/*.parity.test.sh/*-wrapper.sh) — warning.
- B14 ADR integrity — two-format aware. Time-based IDs (
YYMMDD-HH+letter, ADR-FORMAT.md) are not treated as NNNN gaps; NNNN contiguity is checked only over the grandfathered NNNN set (incl. retired/); and a duplicate time-based ID (two ADRs sharing the same YYMMDD-HH+letter) is flagged — error (gap in the NNNN set — warning). (Analogous to A6's task-number uniqueness; keeps the check honest on the repo that dogfooded the time-based scheme.)
- B16 SKILL.md description length — each
skills/*/SKILL.md frontmatter description is measured in Unicode codepoints (locale-independent, matching the /fg menu's char cap and the .js twin) and flagged when it exceeds 600 — warning. The description is dual-use (/fg menu display + auto-invocation trigger, same char cap), so it must stay a terse trigger core; this lint guards that discipline from silently re-bloating (drift, not breakage → warning, per ADR 260716-22a).
Severity: error = state/release actually broken (fix before continuing) · warning = drift that misleads but doesn't block · info = a note.
CI usage (AI-free)
Because the survey is a deterministic script with a clean exit-code contract, a CI job runs it with no AI:
bash scripts/forge-doctor.sh # exit 0 clean · 1 warnings · 2 errors
Wire the gate to your tolerance: fail on non-zero (strict — no warnings allowed) or on >= 2 (block only on errors, allow warnings). It fixes nothing — a failing gate means a human resolves the reported findings locally (fg-quick/fg-ask), then re-pushes. (The example workflow that wires this lives in the team-ci-workflow-merge-policy-docs task.)
fg-doctor (read-only)
│ run forge-doctor.sh (bash) | forge-doctor.js (no bash)
▼
exit 0 ──▶ relay clean bill of health
exit 1/2 ──▶ relay findings (severity · path · fix hint) → state fixes are the human's (fg-quick/fg-ask), auto-fix nothing
Handoff
There is no loop handoff — fg-doctor is self-contained and read-only. Relay the verdict; if there are findings, state that fixes are made via fg-quick (trivial) or fg-ask (non-trivial), and stop — do not auto-invoke either or start fixing (the same restraint as fg-status). If clean, just confirm the clean bill of health.
Constraints
- Read-only. Neither this skill nor the script writes anything — no
.forge/ state, no docs, no fixes. If you find yourself editing a file, you have left fg-doctor's job.
- No auto-fix, no auto-run. It reports; the human fixes on demand. No other skill invokes it.
- No external hard-dependency. The script uses core tools only (bash/coreutils/awk/sed/grep; node for the twin and the JSON-parse check).
Document impact
- None. fg-doctor creates and modifies nothing. It is pure read-only integrity reporting; the survey is
scripts/forge-doctor.sh / .js (ADR-0022 / 260716-16a).
