# grill

Runs six specialized agents (architecture, errors, security, tests, edge cases, recon) in parallel, synthesizes findings into a report with severity tags, file:line references, and a phased fixing plan.

## What it does

Each agent owns its domain: `recon` maps the codebase, `architecture` dissects structure, `error-handling` audits observability and error paths, `security` hunts vulnerabilities, `testing` assesses coverage and CI/CD, `edge-cases` stress-tests race conditions and boundary values. You pick one of five review styles (from quick Architecture Review to Paranoid Mode) and eight optional pressure tests — scale stress, hidden costs, principle violations, success metrics. The report groups findings by severity (`[CRITICAL]`, `[HIGH]`, `[MEDIUM]`, `[LOW]`), each with file path, line numbers, and effort estimate. The fixing plan phases work, graphs dependencies, totals effort.

All agents share the `grill-core` skill, which defines finding format, evidence standards, and the untrusted-input rule. When there are no issues, an agent returns `[GOOD]` — padding to inflate counts is banned. Works in both Claude Code (agents run in parallel) and OpenAI Codex CLI (skills run sequentially), same code on two platforms.

## 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 grill@claude-community
```

## When to use it
- audit project architecture for weak spots and hidden costs
- catch vulnerabilities, data races, and edge cases before production
- get a fixing plan with effort estimates and dependency graph
- run a review in five styles — from quick scan to paranoid mode
- launch eight pressure tests for scale, metrics, and principles

## Example prompts
- Run `/grill:roast` in the project root so six agents check architecture, errors, security, and edge cases in parallel.
- Check only the `src/` directory with `/grill:roast src/` — leave the rest untouched.
- Pick Paranoid Mode and add the hidden-costs pressure test so the `edge-cases` agent also runs.

# grill

[![Validated by NLPM](https://img.shields.io/endpoint?url=https://raw.githubusercontent.com/xiaolai/grill-for-claude/main/nlpm-badge.json)](https://github.com/xiaolai/grill-for-claude/blob/main/nlpm-badge.json)

Deep codebase interrogation — multi-angle architecture review that forces rigorous, actionable analysis. **Works in both Claude Code and OpenAI Codex CLI.**

## What it does

Grill launches 5-6 specialized analysis units in parallel to interrogate your codebase from every angle: architecture, error handling, security, testing, and edge cases. You pick a review style, optionally add pressure tests, and get a comprehensive report with a prioritized fixing plan.

- **6 specialized analysis units**: recon, architecture, error-handling, security, testing, edge-cases (shipped as agents under Claude Code, as skills under Codex)
- **5 review styles**: Architecture Review, Hard-Nosed Critique, Multi-Perspective Panel, ADR Style, Paranoid Mode — plus a "Select All" option
- **8 add-on pressure tests**: scale stress, hidden costs, principle violations, strangler fig migration, success metrics, before/after diagrams, assumptions audit, compact & optimize
- **Evidence-based findings**: every finding requires file paths, line references, severity tags, and effort estimates
- **Fixing plan**: phased action plan (Critical > High > Medium > Low) with dependency graph and effort totals

Part of the [xiaolai plugin marketplace](https://github.com/xiaolai/claude-plugin-marketplace).

## Installation

### Claude Code

Two install paths — both reach the same code. Pick one:

**Via Anthropic's official community marketplace** (curated; updates lag the maintainer's marketplace by up to ~24h):

```
/plugin marketplace add anthropics/claude-plugins-community
/plugin install grill@claude-community
```

**Via the xiaolai marketplace** (latest version lands here first):

```
/plugin marketplace add xiaolai/claude-plugin-marketplace
/plugin install grill@xiaolai
```

> **Install fails with "Plugin not found in marketplace 'xiaolai'"?** Your local marketplace clone is stale. Run `claude plugin marketplace update xiaolai` and retry — `plugin install` does not auto-refresh. (The community marketplace doesn't have this caveat.)

| Scope | Command (xiaolai) | Effect |
|-------|--------------------|--------|
| **User** (default) | `/plugin install grill@xiaolai` | Available in all your projects |
| **Project** | `/plugin install grill@xiaolai --scope project` | Shared with team via `.claude/settings.json` |
| **Local** | `/plugin install grill@xiaolai --scope local` | Only you, only this repo |

The same `--scope` flags work with the `@claude-community` variant.

### OpenAI Codex CLI

Codex installs plugins from a marketplace via an **in-session TUI**, not a shell command. There is no `codex plugin install` verb.

**One-time setup** (shell):

```bash
codex plugin marketplace add xiaolai/claude-plugin-marketplace
```

**Per-plugin install** (inside a Codex session):

1. Start a session: `codex` (in your project directory)
2. Type `/plugins` — opens the plugin TUI
3. Find grill in the `xiaolai` marketplace, install/enable it

## Usage

### In Claude Code: slash command

```
/grill:roast
```

Optionally target a subdirectory: `/grill:roast src/`

### In OpenAI Codex CLI: skill invocation

Codex uses the `$skill-name` syntax, not slash commands. Type either:

```
$grill-roast
```

Or just describe the task in natural language ("do a multi-angle audit of this codebase") and Codex's auto-match will load the skill from its description.

> **Why the difference?** Claude Code maps a plugin's `commands/*.md` files to slash commands like `/grill:roast`. Codex deprecated custom prompts in favor of skills (description-matched on intent), so the same orchestration is shipped as a skill under Codex's layout.

## How it works

1. **Recon** — the recon unit surveys the codebase (structure, stack, size)
2. **Choose review style** — pick from 5 styles + optional add-on pressure tests
