## What it does

This skill establishes a strict privilege boundary during agent optimization. Upstream producers like `/meta-optimize` operate strictly in read-only mode and stage candidate diffs in `.aris/meta/pending/`. No producer can land its own changes. Real corpus modifications happen only through `meta-apply`.

Before writing any changes, the skill initiates a fresh cross-model jury via `mcp__codex__codex` with paths-only context. It ignores pre-screen verdicts in the producer manifest because manifests can be forged. The helper script `provenance.py` ensures the reviewer belongs to a different model family than the author. If the jury issues a KILL verdict or model families match, landing halts immediately.

Operation requires reviewer MCP tools and the `provenance.py` helper in your path. The skill backs up target files to `.aris/meta/backups/`, applies changes with `Write` or `Edit`, and stamps provenance metadata. Direct corpus edits via `Bash` are blocked by design.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill meta-apply -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill meta-apply -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill meta-apply -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install wanshuiyin/Auto-claude-code-research-in-sleep meta-apply
```

2. **Manually: put the files in place**

2. **Platform CLI**
```bash
gemini skills install https://github.com/wanshuiyin/Auto-claude-code-research-in-sleep --path skills/meta-apply
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill meta-apply -a opencode
```

### Claude.ai

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

## When to use it
- prevent unauthorized self-modification loops from mutating skill files
- verify staged diff patches through an independent cross-model jury
- enforce cross-family model separation between patch author and reviewer
- record provenance receipts and backups before altering the skill corpus

## Example prompts
- /meta-apply 1,3
- land the staged patches
- /meta-apply all

This skill exists to enforce a **privilege boundary**. Producers like
[`/meta-optimize`](../meta-optimize/SKILL.md) (and, later, `corpus-audit`) are
**read-only** — no `Write`/`Edit`, no apply step; they can only *stage* candidate patches
under `.aris/meta/pending/`. **This skill is the only place a staged patch becomes a real
change to the corpus.** Splitting "propose" from "land" across two skills with different
tool grants is what makes "a loop cannot apply its own patch" structural rather than a
sentence the producer is asked to obey.

It is **human-invoked only.** It runs when the user explicitly types `/meta-apply` after
reading the producer's REPORT. That invocation IS the landing authorization (the locked
2026-05-30 decision: the human stays at the landing gate).

## The acquittal is generated HERE, not relayed

The earlier design trusted a `jury_verdict: pass` field in the producer's manifest. That
is **forgeable** — the producer writes that field, so a buggy/misaligned producer could
stage a killed patch labelled "pass." **So this skill does not trust any producer-written
