Specwright Doctor

Goal

Validate that a Specwright installation is coherent across the tracked project-artifact root, shared repo-state root, and per-worktree session model, then print actionable repair hints using the same runtime-root and ownership vocabulary the adapters expose.

Inputs

• {projectArtifactsRoot}/config.json
• {projectArtifactsRoot}/CONSTITUTION.md and {projectArtifactsRoot}/CHARTER.md
• {worktreeStateRoot}/session.json when present
• {repoStateRoot}/work/*/workflow.json
• {workArtifactsRoot}/{workId}/approvals.md and {workDir}/review-packet.md when present
• gate skill files, hook config, and configured commands

Outputs

• PASS/WARN/FAIL health table
• Optional backfill of prNumber and prMergedAt on the owning work's workflow.json

Constraints

Pre-condition (LOW freedom):

• If neither the shared layout nor the legacy fallback can be resolved, stop immediately and tell the user to run /sw-init.
• Always report layout status first: shared/session, legacy fallback, or missing.
• When layout resolves, describe the active runtime mode explicitly: project-visible runtime roots under .specwright-local/ are the preferred interactive default; git-admin roots under .git/specwright/ are compatibility mode.

Checks (LOW freedom — run all 13 in order):

1. Anchor docs — tracked Constitution and Charter exist and are non-empty
2. Config — tracked config parses and contains gates and git
3. State — current session parses when present, every discovered workflow parses with a null or fresh per-work lock, and layout status is explicit
4. Gates — enabled gate skills exist
5. Build command — configured build command exists on PATH
6. Test command — configured test command exists on PATH
7. Format/lint — configured format or lint commands exist on PATH
8. Hooks — hook manifest parses and referenced hook files exist
9. Backlog config — configured backlog target is usable
10. ast-grep — INFO availability only
11. OpenGrep — INFO availability only
12. LSP — PASS/WARN/INFO based on available platform or standalone LSP
13. STATE_DRIFT — enumerate repo-wide workflows and flag shipped units with status=shipped and prNumber=null

Within the State pass, check all of the following and report them by name:

• layout status for the current checkout
• resolved projectArtifactsRoot, workArtifactsRoot, and the authoritative runtime roots (repoStateRoot and worktreeStateRoot) for the current checkout
• session attachment consistency between session.json and the owning workflow.json
• dead sessions where a recorded attachment points at a missing or removed worktree
• legacy-write drift where the shared layout exists but checkout-local legacy state files are still being treated as writable sources
• approval freshness for the selected unit when approvals exist
• review-packet presence for the selected unit when verify or ship artifacts should exist
• live ownership conflicts that should route the operator to /sw-adopt instead of implying generic takeover

State-pass output must report the authoritative runtime roots clearly so the user can see which repoStateRoot and worktreeStateRoot are in force.

Within the Config pass, check all of the following and report them by name:

• queue validation without the required provider-aware configuration surface
• Claude-oriented installs that remain on git-admin even though project-visible runtime roots are the recommended default for that setup
• work-artifact publication mode that points at clone-local runtime roots, session state, or symlinked .git mirrors instead of an explicit tracked artifact path
• config.git.runtime.projectVisibleRoot values that point at tracked project artifacts or .git-mirrored paths instead of a dedicated project-visible runtime root

Reject project-visible roots that overlap tracked project artifacts or .git-mirrored paths, and name config.git.runtime.projectVisibleRoot in the result.

CONFIG_MISMATCH findings must name the offending config key and print the corrective action.

STATE_DRIFT findings must print the inline remediation command sw-status --repair {unitId} and include the owning work ID.

STATE_DRIFT backfill (MEDIUM freedom):

• On the first invocation, attempt a one-time backfill for any shipped unit with status=shipped and prNumber=null.
• Candidate set: shipped units with prNumber=null across all discovered workflows.
• Detection order is strict: gh lookup, then git log / merge confirmation, then warn and leave the fields untouched.
• Backfill order is gh, then git log, then warn.
• Backfill scope is limited to prNumber and prMergedAt on the owning work's workflow file.
• Backfill never modifies status; it only writes prNumber and prMergedAt.

Output format (MEDIUM freedom):

• Print the same PASS/WARN/FAIL/INFO table shape as the existing doctor output.
• STATE_DRIFT findings must include the owning work ID and unit ID so the user can distinguish repo-wide issues.

Workflow mutation scope (LOW freedom):

• The only allowed mutation is STATE_DRIFT backfill.
• When mutating a work's workflow.json, follow protocols/state.md.
• Doctor never modifies status; only prNumber and prMergedAt may change.
• It is not a core workflow stage and never claims top-level work ownership.
• Any repair guidance beyond PR backfill must remain bounded to the documented migration surface: tracked docs/config under {projectArtifactsRoot}, split per-work workflows under {repoStateRoot}, and this worktree's {worktreeStateRoot}/session.json.

Failure Modes

Condition	Action
shared config missing	fail that check and continue
workflow parse error	fail the state check and identify the owning work
all checks pass	print the table and say all checks passed
hooks absent	INFO: no hooks configured
