Conciseness

Lean and repo-specific throughout — every line carries paths, commands, or env vars Claude could not infer ('pnpm world up dev-app-web --detach -- --browser', 'OPENWORK_EVAL_MYSQL_URL=...'). No explanation of known concepts; the one-sentence philosophy ('A change is done when you have watched it work...') earns its place as framing.

Actionability

Fully executable: exact commands for every step (start/teardown, e2e runs, 'git worktree add /tmp/ow-base origin/dev' with the copy/run sequence for the fails-on-dev check), concrete file paths, and per-change-type test locations in a decision table.

Workflow Clarity

Five clearly sequenced steps with an explicit validation checkpoint at step 4 ('must fail' on dev / 'must pass' on branch) and a remediation loop ('If it passes on dev, the assertion is looser than the change: tighten it'). The decision table in step 1 routes change types to the right check.

Progressive Disclosure

Well-organized sections with clearly signaled one-level references to sibling skills ('write-a-spec', 'drive-desktop-cdp', 'open-a-pr'). However, the nine-core-journeys feature map table is reference-grade detail inlined in the main body; moving it to a reference file would keep SKILL.md a tighter overview. Not a 5 because content split is imperfect; not a 3 because navigation and signaling are clean.

Specificity

Lists multiple concrete actions — 'Start the product', 'drive the change the way a user or client would', 'capture screenshots', 'show the proof fails on dev and passes on your branch' — with comprehensive coverage of what the skill does. No mere domain-naming; well above the 'several specific actions, minor gaps' level.

Completeness

Explicitly answers both 'what' (prove, start the product, drive, capture screenshots, fail-on-dev/pass-on-branch) and 'when' with three concrete trigger phrases ('before opening a PR', 'reviewer asks "show me"', 'core journey is red').

Trigger Term Quality

Good natural triggers — 'Use before opening a PR', 'when a reviewer asks "show me"', 'when a core journey is red' — but misses common synonyms users would say ('verify', 'demo', 'e2e') and leans partly on internal jargon ('core journey'). Not a 5 because synonym-level coverage is absent; not a 3 because the PR/'show me' phrasing is genuinely what users say.

Distinctiveness Conflict Risk

Names a clear niche (OpenWork verification on the real product) with distinct triggers tied to PR/reviewer/journey contexts; minimal conflict risk with generic skills.
