Usage

/runbook                              # Auto-detect feature, create or update
/runbook <feature-keyword>            # Specify feature
/runbook --update                     # Force update mode
/runbook --check                      # Read-only staleness validation
/runbook --request <path|title>       # Specify target request (multi-request features)

Phase 0: Context Resolution

Resolve feature using the 5-level cascade:

The wrapper, not the CLI directly: resolve-feature.js owns the failure payload, so the full shape with scan_error: true arrives however the CLI fails — a nonzero exit, a signal, a partial write, a payload that is not the agreed shape. (It cannot survive node itself being unavailable: nothing running under node can. What it removes is the CLI's failure domain, not the interpreter's.) Calling the CLI with || echo '{}' produces a payload the gate below cannot recognise as a failure.

Decide the branch yourself, then run one command. This skill grants Bash(node:*), which matches a direct node … invocation and nothing else — a shell if/[ … ]/$(…) compound is not a node command and cannot run here. Parse $ARGUMENTS first (Step 1 below), then issue exactly one of:

node scripts/resolve-feature.js --feature <the feature key from $ARGUMENTS>

node scripts/resolve-feature.js

Use the first when $ARGUMENTS carried a positional feature key, the second otherwise. Pass the key as a separate argv token — never interpolate it into a larger shell expression.

`scan_error` gate. Gate on `scan_error !== false`, not on scan_error === true. When it

is not exactly false the four source sets are unknown, not empty — the corpus could not be

enumerated (unreadable directory, broken taxonomy, no repository), or the resolver never ran

and a shell fallback supplied a payload with no such field at all. {} is the shape that made

the stricter test useless: it has no scan_error, so === true is false and the gate passes a

payload that contains nothing. Do not proceed as though the feature has no authority documents —

report and take the ⚠️ Need Human exit. A key may still be present, so a non-null key is not

evidence the sets are complete.

Note: Mode dispatch keys off the specific file runbook-release.md, not any runbook-typed doc in doc_inventory. A feature may have runbook-deploy.md (a different topic) without triggering update mode for the release runbook.

Request Selection

Phase 1: Content Discovery (Create/Update modes)

Use scoped discovery cascade — narrow to wide, with confidence degradation:

A P1 path is classified before it is used. Related Files is High confidence because the request author named those paths deliberately — not because a path in that table is exempt from the role split. Resolve each one first: a path landing in design_records (a tech spec, an architecture doc) is treated as P3 — Medium, marked unverified — even though it arrived via P1. Otherwise the row the split removed comes straight back through the front door, since a request's Related Files table routinely names 2-tech-spec.md.

Priorities 2 and 3 used to be one row reading "canonical docs (tech-spec, architecture) — High", which is the confusion this feature exists to remove: a tech spec is a design record, and a runbook built from one describes a procedure that may never have been built.

See references/discovery-heuristics.md for per-section mapping.

Security — Redaction Rules

When mining configs/workflows/logs into committed markdown:

Phase 2: Generate / Update

Create Mode

1. Read current_authority first — a runbook describes what operators will actually run, so the

sources are code, rules/, and the docs that claim to be current. Fall back to design_records (tech spec, architecture) only for the intent behind a step, and mark any step sourced that way as unverified in the provenance manifest: a design record may describe a procedure that was never built

1. Read active request(s) by enumerating docs/features/{feature}/requests/*.md — not by

filtering work_records. That set answers "is this document a work record", and a ticket that resolves to some other role — authority Yes, or a Doc role naming one of the other three — leaves it while staying an open ticket; selecting from the set would drop exactly that ticket's AC, scope and related files

1. Run scoped discovery for each template section
2. Fill template from references/template.md
3. Embed <!-- runbook-provenance --> manifest with source SHAs
4. Write to docs/features/{feature}/runbook-release.md

Update Mode

1. Read existing runbook-release.md and parse <!-- runbook-provenance --> block
2. Compare each sources[].sha against git hash-object <file>
3. Identify stale sections (any source SHA mismatch)
4. Re-run discovery for stale sections only
5. Edit stale sections via Edit tool (preserve fresh sections)
6. Update provenance manifest with new SHAs

Phase 3: Check Mode (--check)

Read-only validation — does not modify the runbook file.

1. Read existing runbook-release.md and parse provenance manifest
2. For each section, compare sources[].sha against current git hash-object
3. Classify: Fresh / Stale / Missing / Unknown (see references/check-output.md)
4. Output report with per-section status and SHA diffs
5. Emit verdict: Ready / Stale / Incomplete

Output

Verification

• [ ] Feature resolved via node scripts/resolve-feature.js, and scan_error was exactly false
• [ ] Runbook detected in doc_inventory (ancillary/runbook type)
• [ ] Template has all 9 sections (see references/template.md)
• [ ] Provenance manifest embedded with multi-source SHA tracking
• [ ] Discovery uses scoped cascade (not repo-wide grep as first option)
• [ ] Redaction rules applied (no secrets in committed markdown)
• [ ] --check mode is read-only (no file writes)
