SKILL.md (first lines)

Read [the native runtime contract](../dav-mode/references/playbook-runtime.md) before executing. It maps the Cursor tools, model examples, configuration paths and cloud placements below to actual native capabilities. Those examples do not authorize unsupported calls, delegation, model campaigns, publication or desktop access. Keep the full method and report an unavailable required capability as a gap.

## Runtime adaptation

Read [shared working rules](../dav-mode/references/working-rules.md) and
[playbook runtime](../dav-mode/references/playbook-runtime.md). Locate native
project skills in `.agents/skills/verify-*/`, `.claude/skills/verify-*/`, or an
existing `.cursor/skills/verify-*/`. Multiple candidates require a target.
Follow [create-verification-skill](../create-verification-skill/SKILL.md) for a
missing target. This import supplies the maintenance loop it previously lacked.

Use the native child API for the source wave only when delegation is explicitly
authorized. Give each read-only child one feature and the desktop restrictions.
Follow native start, report, and stop semantics. Without authorized delegation,
source reading may proceed serially, but report the independent source wave as
not run and do not call the complete upstream pass clean.

Only the coordinator drives the app. Follow its Launch, Doctor, isolation, and
Cleanup instructions. Use owned terminal/API interactions or the configured
browser skill. Native GUI activation or system-wide input needs permission for
that run. Preserve the clipboard, disable test audio, and never drive the user's
instance. Retain evidence through every cleanup, including failed attempts.

Use jj, not Git mutation, in colocated repositories. A changed outcome returns
a proven scoped diff when PR creation or publication is not authorized. Do not
open, push, or merge a PR merely because this skill says to ship. Keep product
regressions outside the verification-directory edit scope.

# Maintain a verification skill

A feature map rots the moment the app changes. This skill is the upkeep loop for a skill generated by `/create-verification-skill` (or any project-local verification skill with a feature map). The unit of rigor is the feature, not every sentence: cover every feature file from source and exercise every feature live, without terminalising every bullet.

## Outcomes

Pick one, and say which:

- **clean** — every feature got source and live coverage; nothing worth shipping. No branch, no PR.
- **changed** — one PR ships proven doc, harness, or map corrections.
- **blocked** — coverage could not finish or a proven fix could not ship safely. Say exactly what blocked it.

## Edit scope

Only edit the verification skill's own directory (its SKILL.md, features/, and any harness scripts it owns). Never edit product code during a run: a behavior the map describes that the app no longer does is either doc drift (fix the map) or a product regression (report it, don't paper over it in docs).

## Pass

0. **Locate the target.** Find the verification skill to maintain: the project-local skill whose body has launch/drive sections and a feature map (usually `.agents/skills/verify-*/`). Several candidates → ask which one; none → stop and point at `/create-verification-skill` instead of inventing a target.

1. **Index hygiene.** Read the feature map README and glob its sibling files. Fix missing, extra, duplicate, or dead entries. Lightweight; no generated inventory.

2. **Source wave.** One read-only subagent per feature file, launched concurrently. Each explains "how does this user-facing feature work?" from source, flags likely doc drift with citations, and returns one concise live-verification recipe. Children never drive the app and never edit files. Return shape: feature summary / source entry points / likely drift or none / one recipe.

3. **Reconcile.** Every feature file has a returned summary. Merge overlapping recipes into as few app states as practical. Spot-check cited drift; don't re-prove clean claims. Sweep recent churn for user-facing surfaces missing from the map — require a concrete source path before calling one missing.

4. **Live pass.** Required even when source looks clean. The coordinator owns all driving; follow the verification skill's own launch model — one long-lived instance driven serially for servers and UIs, or a fresh isolated session per drive for short-lived CLIs (the skill's Launch section decides, not this one). Exercise every feature at least once, and hold three invariants the whole pass, whatever the failure: (1) never drive an instance you haven't health-checked since it last did something surprising — doctor before first drive, doctor on each fresh session where sessions are the unit, doctor again after any failed drive, and where doctor can't see the failure (a wedged UI state on a healthy process), reset to a known state or relaunch rather than hoping; (2) evidence captured so far survives every cleanup, checked at its named location, not assumed; (3) nothing a drive started outlives that drive's usefulness — failed-iteration residue is cleaned whether the session is stuck, exited, or shared (for a shared instance, clean the residue, not the instance). A doctor failure caused by skill drift is drift: fix it under edit scope and retry once — restart whatever the fix invalidated, nothing more — before calling the pass `blocked`. A feature that can't be reached is `verified-unreachable` only with the concrete prerequisite (auth, entitlement, OS, external state) and the route attempted; if the map omits that prerequisite, that's drift. Any harness fix from triage gets re-driven live before it ships. Final teardown happens after the last drive of the run — including those re-proofs — so nothing outlives the run (evidence stays, per the skill).

5. **Triage.** Wrong or missing user-POV description → doc drift, fix it. Working behavior the harness can't drive → harness gap, fix it; a harness fix follows the same helpers rule as generation (scripts executable, invocation documented in the skill body). App behavior that's actually broken → product gap; record it for the user, keep it out of this PR.

6. **Ship or stop.** For changed: one PR of proven corrections, re-read every changed file first. For clean or blocked: no PR, report the outcome and the coverage honestly.

Keep concise run notes (features covered, unreachable prerequisites, confirmed drift, outcome) in a scratch location; don't commit them.
