# codex-bridge

Runs Claude review, adversarial review and second-pass handoffs from inside Claude while ThumbGate memory and pre-action gates stay in the loop.

## What it does

The plugin adds slash commands to Claude that hand work to Claude: a standard review, an adversarial one, and a second pass over what was already done. Each call goes through ThumbGate, the local pre-action layer that keeps a memory of past failures and decides whether a tool call should proceed.

The wiring is straightforward. A plugin command builds the Claude request, and ThumbGate stays in the cycle applying its gates to the proposed calls, so a review does not switch off the protection you already configured. If ThumbGate is missing or its hook never fires, the pairing loses its point — check that the gate runs at all before relying on it.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install codex-bridge@claude-community
```

## When to use it
- run a second review pass over a fresh patch
- get an adversarial read on a design from another model
- send code checks to Claude without leaving Claude
- keep ThumbGate gates active during an outside review

## Example prompts
- Run a Claude review on the changes in this branch
- Do an adversarial Claude review of this patch
- Hand the second pass over `src/api.ts` to Claude

## What it does

ThumbGate is the local-first **Pre-Action Checks** engine for AI coding agents. It runs in the PreToolUse hook to evaluate the proposed tool call before execution — so costly mistakes can be caught before they happen.

ThumbGate GitHub star growth is measured with GitHub's privacy-safe [`GET /repos/{owner}/{repo}/stargazers/history`](https://docs.github.com/en/rest/activity/starring#get-repository-star-history) endpoint (weekly counts, no stargazer identities). Run `npm run stars:history -- --fixture tests/fixtures/github-star-history.json --json` for the local proof. Stars are not npm installs and not revenue. The live GitHub Marketplace Action is [ThumbGate Agent Governance](https://github.com/marketplace/actions/thumbgate-agent-governance) (`uses: IgorGanapolsky/ThumbGate@v1`).

**Usage over star count.** Evaluate ThumbGate from the install path and live usage badges above (`npx thumbgate init`, Marketplace `uses:`, npm weekly downloads, GitHub clones), not from whether the repo has twenty stars or twenty thousand. No pitch deck is required. We do not farm GitHub profile badges (no YOLO-merge of protected `main`, no 5-minute Issue close theater, no fake `Co-authored-by`). Galaxy Brain needs real accepted answers in [Discussions Q&A](https://github.com/IgorGanapolsky/ThumbGate/discussions/categories/q-a). `npm run github:achievements -- --fixture tests/fixtures/github-achievements.json --json` inventories what is already earned vs what we refuse to farm.
