## What
Wave 1 of **ag-okfu** — adds an explicit `Use when:` discovery trigger
clause to the 8 **judgment-tier** skills: `council`, `design`,
`post-mortem`, `pre-mortem`, `red-team`, `review`, `validate`, `vibe`.
`scan_descriptions.py` flagged 73/81 skills with no trigger marker — a
silent skill-selection risk since runtime discovery is pure LLM
reasoning over the `description` field. The judgment tier ships first
because mis-selection there (e.g. grabbing `review` when you needed
`validate`) is the most costly.
## Why this slice
The bead says *"wave by metadata.tier."* This is one coherent wave = one
PR with a single rollback semantic. Remaining tiers (execution 22,
knowledge 8, meta 8, session 6, background 5, product 5, contribute 4,
cross-vendor 3, library 3, orchestration 1) ship as follow-on waves.
## Evidence
- Corpus missing-trigger count: **73 → 65** (the 8 judgment skills now
pass).
- `python3 skills/skill-builder/scripts/scan_descriptions.py skills
--strict` — all 8 judgment skills report `has_trigger=True`.
- `bash scripts/generate-registry.sh --check` → `OK: registry.json is up
to date` (regenerated, descriptions embedded).
- `markdownlint` clean on all 8 changed SKILL.md files.
## Notes
- Does **not** close ag-okfu — the `--strict` gate stays red until all
tiers are done. Advances the bead; unblocks nothing yet (ag-cx7d ratchet
waits on full corpus clean).
Bounded-context: BC1-Corpus
Evidence: skill-domain-map golden gate
#275's billboard refactor thinned process-skill SKILL.md files and moved
detail into references/, but the validate contracts still grepped SKILL.md.
skill-lint + smoke-test: relax content-presence checks in crank/implement/
post-mortem/swarm validate.sh to scan the skill as a unit (SKILL.md +
references/); structural/identity checks stay SKILL.md-only. test-first-smoke
updated to match relocated SPEC/TEST WAVE + Step 0/4 headings.
skill-lint line caps: trim flywheel 310 -> 286 (cap 300), using-agentops
261 -> 239 (cap 250) by removing redundant prose, no content lost.
skill-integrity: link 3 orphaned references (crank/branch-isolation,
validation/flags + release-readiness-gates).
codex parity: regenerate stale skills-codex source hashes (77 skills).
Local: run-all.sh PASS, heal.sh --strict clean, smoke-test PASS.
