# maintain-verification-skill

Keep a project's verification guide and feature map aligned with its code. The skill checks each mapped feature against the live app and flags confirmed fixes.

## What it does

The skill locates a project verification skill, checks its feature map against the neighboring files, and sends a read-only source review to each feature file. It then exercises every feature in the running app. Documentation drift and harness gaps can be fixed; broken product behavior is reported separately.

Changes stay inside the verification skill's directory, including its `SKILL.md`, `features/`, and owned scripts. A changed run can produce one PR containing proven corrections. The live pass is required even when the source review finds no drift. When a feature cannot be reached, the skill records the prerequisite and attempted route; missing prerequisites in the map count as documentation drift.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --skill maintain-verification-skill -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/maintain-verification-skill/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/maintain-verification-skill/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --skill maintain-verification-skill -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/maintain-verification-skill/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --skill maintain-verification-skill -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/maintain-verification-skill/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install backnotprop/pstack maintain-verification-skill
```

2. **Manually: put the files in place**
- File: `.github/skills/maintain-verification-skill/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --skill maintain-verification-skill -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/backnotprop/pstack --path skills/maintain-verification-skill
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/maintain-verification-skill/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add backnotprop/pstack --skill maintain-verification-skill -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/backnotprop/pstack/tree/HEAD/skills/maintain-verification-skill/SKILL.md

## When to use it
- compare a feature map with its files
- spot outdated feature descriptions against source
- exercise mapped features in the live app
- separate product regressions from harness gaps
- prepare one PR with verified corrections

## Example prompts
- Run `/maintain-verification-skill` to audit the project's feature map.
- Use `/maintain-verification-skill` to compare the verification guide with the current app.

# 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 `verify-*/` in the project's skill folder: `.cursor/skills/`, `.claude/skills/`, `.pi/skills/`, or `.agents/skills/`). 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.
