# verification-before-completion

This skill checks whether the evidence supports a completion claim, from a fix report to commit readiness. Use it when closing out code changes or handing work over.

## What it does

Before reporting a task as done, the skill calls for current evidence, a check matched to the claim, and a clear account of what remains uncovered. Partial results call for a narrower conclusion, not a full-completion claim. For small or read-only work, a concise statement can cover the check, result, risk, and confidence.

For interface changes, it incorporates checks of user-facing criteria. For fixes, it separates the cause from the verified outcome and asks whether existing behavior still holds. Git closeout compares task changes with their starting state and records commit details; task cleanliness and repository cleanliness stay separate. A failed verification or commit hook blocks a clean-completion claim.

The skill does not authorize destructive work or decide that requirements have been accepted. Stale or incomplete evidence limits what you can claim. In Claude Code, install it with `npx skills add GanyuanRan/Aegis --skill verification-before-completion -a claude-code`; its file is at `~/.claude/skills/verification-before-completion/SKILL.md`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add GanyuanRan/Aegis --skill verification-before-completion -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add GanyuanRan/Aegis --skill verification-before-completion -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add GanyuanRan/Aegis --skill verification-before-completion -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install GanyuanRan/Aegis verification-before-completion
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add GanyuanRan/Aegis --skill verification-before-completion -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/GanyuanRan/Aegis --path skills/verification-before-completion
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add GanyuanRan/Aegis --skill verification-before-completion -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/GanyuanRan/Aegis/tree/HEAD/skills/verification-before-completion/SKILL.md

## When to use it
- check whether test results support a completion claim
- mark unchecked scope and remaining risk
- compare a fix with its cause and preserved behavior
- record verification and Git state before handing work over

## Example prompts
- Check whether the latest results support calling this task complete.
- Compare the fix with the reported cause and identify anything still untested.
- Before committing, review this task's changes and report the repository state separately.

# Execute

Before success claim: classify destructive permission; read sufficient current
evidence and run a fresh falsifying check when it is missing or invalidated;
read the complete result/scope; select L0/L1/L2. Downgrade for partial,
stale, failing, or narrower evidence; never claim complete then verify later.

This pack grants no `GateDecision`, `PolicySnapshot`, evidence sufficiency,
requirement acceptance, or completion authority.

## Stop Signals

- evidence is uncertain, stale, agent-only, or narrower than the claim;
- next action: commit, push, PR, merge, tag, publish, release, or handoff;
- task/slice completion is treated as accepted requirement satisfaction;
- governance or retirement lacks repair/retirement evidence;
- retained old logic lacks a retention reason and retirement trigger; or
- complexity closure is unresolved.

Destructive/irreversible work needs scoped permission; broad assent is not scoped permission.

## Required Evidence Slots

For changed interface/interaction claims, compose `ui-ux-governance` verification;
carry results and uncovered user criteria here, keeping one closeout owner.

```text
- Evidence action / check performed:
- Result / exit status:
- Covered scope:
- Uncovered scope:
- Residual risk:
- Confidence grade: A | B | C
```

- `A`: target + regression; no meaningful unknown.
- `B`: target evidence; bounded residual risk.
- `C`: partial only; no full-completion claim.

For repairs/optimization, distinguish cause, closure and verified outcome.
Check interactions and preserved behavior; investigate consequential unknowns.

Claims need target test and related regression evidence at the triggering seam.
A missing seam is an architecture gap; blocked automation needs reproducible
manual steps. Both limit confidence.

Read the smallest source for each explicit baseline/artifact/owner/contract/evidence
reference. Mark it preserved, rebound to its canonical owner, retired with reason,
