# verify

Runs a self-healing Rust verification loop using cargo test, clippy, and fmt. It prevents false passes by enforcing actual test execution before review.

## What it does

The skill automates Rust project checks in a strict sequence: `cargo test --quiet`, `cargo clippy --all-targets --all-features -- -D warnings`, and `cargo fmt --all -- --check`. When a step fails, the agent inspects compiler or linter errors, modifies the source code, and retries. If the exact same failure occurs 3 times in a row, the loop stops to notify the user.

Verification honesty rules prevent false green reports. Skipped tests marked `#[ignore]` or runs blocked by missing external services count as unresolved blockers instead of passes. Mock-only coverage must be explicitly flagged in the report as unconfirmed integration.

The workflow depends entirely on an active Rust toolchain with Cargo. Once all checks run honestly without blockers, the agent immediately triggers `/review` without asking for confirmation.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mag123c/toktrack --skill verify -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mag123c/toktrack --skill verify -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mag123c/toktrack --skill verify -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mag123c/toktrack verify
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mag123c/toktrack --skill verify -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mag123c/toktrack --path .claude/skills/verify
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mag123c/toktrack --skill verify -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/mag123c/toktrack/tree/HEAD/.claude/skills/verify/SKILL.md

## When to use it
- run Cargo test, Clippy, and formatting checks before committing
- fix compiler and linter errors automatically in a retry loop
- stop unrun or ignored tests from masquerading as verified passes
- trigger the `/review` step right after all verification gates clear

## Example prompts
- Run the verify loop on this crate before making a commit
- Check the Rust codebase and fix any clippy warnings automatically
- Verify test execution and report unresolved blockers

# Verify

## Flow
```
cargo test → cargo clippy → cargo fmt --check
    │            │              │
    └── On fail: fix and retry (notify user after 3 same failures)
```

## Commands
```bash
cargo test --quiet
cargo clippy --all-targets --all-features -- -D warnings
cargo fmt --all -- --check
```

## Verification Honesty (MUST — PASS gate)

Verification trustworthiness lies not in "what passed" but in **"what was *actually executed* and passed"**. Enforced before any PASS verdict.

### Skip ≠ Pass
- Tests marked `ignored` / `#[ignore]` are **unverified** → do not count as green.
- Tests skipped due to environment (missing external service, platform constraints, etc.) are a **BLOCKER**. If unfixable, escalate to user as "verification incomplete + reason" rather than PASS.

### Do not cite unrun tests as verification evidence
- "Confirmed via test X" is only valid when **that test actually ran and passed in this execution**.
- Do not use a merely written test as evidence of "confirmed" (false-green = false reassurance).

### Coverage honesty (mock ≠ real)
- Mock-based unit tests verify **only the logic inside the mock boundary**. Behaviors invisible to mocks — file I/O, concurrency, simd-json real parsing — are **confirmed only by integration verification**.
- If a path is covered only by mocks, report it as **"mock coverage only — integration unconfirmed"** rather than "verified".

### Acceptance/DoD cross-check (carry PLAN gates)
- Read the PLAN Acceptance/DoD and any `[unverified-gate]` passed from implement; cross-check whether each item **actually ran and passed in this execution**.
- If unrunnable (prod smoke / external service / CI-only environment) → no green-wash. Tag as `[unverified-gate: delegated, owner/due/probe]` and **carry to wrap Plan Reconciliation** (`../wrap/references/reconciliation.md`).

### Report format
- ✅ Actually executed and passed
- ⛔ Skipped/environment-blocked + **reason** (unresolved = BLOCKER, not PASS)
- ⚠️ Mock coverage only, integration unconfirmed
- ⏳ Delegated to wrap due to unverifiable Acceptance item

## Self-Healing
- Fail → analyze error → fix code → retry
- Same error 3 times → notify user

## Rules
- Required before commit
- Order: test → clippy → fmt
- All must pass to proceed

## Next Step
**Only when the Verification Honesty gate passes** (actual execution passed, no unresolved BLOCKERs) → call `/review` immediately. Do not ask "should I review?".

If there are unresolved BLOCKERs, **do not proceed to /review** — report "verification incomplete + reason + required environment actions" to the user.
