## What it does

This skill sits between "the lanes are done" and "commit or push". It inventories every planned lane, keeps missing, declined, cancelled, timed-out and failed states apart, and compares changed files against each lane's declared scope. Unexplained drift is a FAIL. A claimed success with no evidence stays unverified.

Presets fire on what the diff contains. Two or more locale variants of one file stem pull in `multi-locale-mirror-sync`; new catalog or listing entries pull in `catalog-entry-add`; a named frontier model with a benchmark number, release date or license claim pulls in `fact-check-frontier-models`. These are declarative review contracts under `presets/`, not an engine — you follow their checks by hand. Matching heading counts or line counts proves nothing about meaning, so disagreements get quoted.

The skill never commits, merges, pushes or deletes branches, and it will not turn a decline, cancellation, timeout or failure into a pass. Numeric budgets and retry limits come from the project's policy rather than from the skill itself. In harness mode an unreadable policy, plan or checkpoint is a fail-closed blocker: stop and report it. A human can approve a documented exception, but the original gate record stays as it was.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add WenyuChiou/agent-collab-skills --skill agent-acceptance-gate -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add WenyuChiou/agent-collab-skills --skill agent-acceptance-gate -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add WenyuChiou/agent-collab-skills --skill agent-acceptance-gate -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**

## When to use it
- reconcile several subagent results before committing
- catch drift between locale variants of one file
- confirm a lane's changed files match its declared scope
- separate an unverified success from one backed by evidence
- record a human exception without rewriting the gate result

## Example prompts
- Run agent-acceptance-gate on this diff before I commit and give me the verdict with evidence
- Reconcile the lane results and list what was filtered out and why
- Run the multi-locale-mirror-sync preset over the changed locale files

description: Use when about to commit or push a diff that touches two or more locale variants of one file stem, adds catalog or listing entries, states benchmark numbers, release dates, or licenses for named frontier models, or merges output from any subagent or delegate. Reconciles the lane results, runs the matching preset, and returns PASS, CONDITIONAL PASS, or FAIL with evidence.

# agent-acceptance-gate

The read-only check between "the lanes are done" and "commit or push". It
reconciles results, runs the triggered presets, and returns a verdict. It
never merges, commits, retries, or turns a decline, cancellation, timeout, or
failure into success. Since 0.6.0 it includes the former
`agent-output-reconciler`.

## Inputs

- the lane table or plan: lane ids, roles, scopes, acceptance criteria;
- each lane's returned summary, evidence paths, and log paths;
- the merged diff and the project's verification commands;
- in harness mode, the `TaskCheckpoint` and latest `PolicyDecision`;
- prior human decision records, if any.

Historical provider fields may be read for migration only. Current checks use
lane or task ids and roles.

## Step 0: Harness mode only

Validate the plan, checkpoint, and policy before anything else. An unreadable
configured policy, plan, or checkpoint is a fail-closed blocker: stop and
report it. Do not infer missing policy values.

## Step 1: Reconcile

1. Inventory every planned lane. Keep missing, `null`, declined, cancelled,
   timed-out, degraded, and failed as distinct states. Never invent an absent
   result.
2. Filter unusable results out of synthesis and record what was filtered and
   why. A completed prose result is not `null` just because an optional
   structured-output step failed.
3. Compare changed files with each lane's declared scope. Record justified
   transitive changes separately; unexplained drift is FAIL.
4. Bind each result to its task, attempt, and baseline with the
   [task-content evidence review](../../docs/task-content-evidence.md). Stale
   or wrong-task evidence stays unverified. Account for pre-existing dirty
   state and parallel writers before attributing a change. File times alone
   cannot prove or disprove success.
```
