meta-apply

meta-apply is an open-source data skill for Claude Code and compatible agents, published by wanshuiyin. Its author describes it as: “Privileged applier that LANDS meta-optimize / corpus-audit patches the user approved — the ONLY skill permitted to mutate the skill corpus from a self-modification proposal, with cross-model jury and human approval at…”. The project has 15k stars on GitHub and is available under the MIT license. Add it to your setup with `git clone https://github.com/wanshuiyin/Auto-claude-code-research-in-sleep ~/.claude/skills/meta-apply`.

What meta-apply does

This skill exists to enforce a **privilege boundary**. Producers like `/meta-optimize` (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.

Installation

Add meta-apply to your agent with:

git clone https://github.com/wanshuiyin/Auto-claude-code-research-in-sleep ~/.claude/skills/meta-apply

• Provenance is a receipt, not an acquittal of correctness
• Key Rules
• Review Tracing
