What is claude-plugins AGENTS.md?

A repository guide for a collection of related Claude plugins kept in one codebase, called a monorepo. It describes the folder layout, development commands, coding conventions, and testing rules.

Use it when developing, testing, reviewing, or organizing the repository's plugins, Python tools, documentation, and shared files.

It gives an agent the project-specific steps needed to change plugins safely and verify the results.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00810	$0.00810
Opus 5.5	$0.00324	$0.00324
Sonnet 5.5	$0.00162	$0.00162

Security

Grade A, and why

claude-plugins AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Repository Guidelines

Project Structure & Module Organization

This repository is a plugin monorepo under plugins/.

plugins/code, plugins/code-review, plugins/judges, plugins/bootstrap, plugins/platform, plugins/self-learning
Each plugin typically contains .claude-plugin/ (manifest), agents/, commands/, skills/, tools/, prompts/, scripts/, schemas/, and plugin-specific docs or resources.
Shared docs are in docs/ (glossary, dependency map), and repository-wide guidance is in README.md, CONTRIBUTING.md, and CHANGELOG.md.
Plugin Python code/tests live under plugin subdirectories, e.g. plugins/code/tools/python/ and plugins/code-review/tools/python/.

Build, Test, and Development Commands

python3.13 -m venv .venv && source .venv/bin/activate
Create an isolated environment for local development.
pip install ruff pyright pytest
Install core developer tooling.
pip install -r plugins/code/tools/python/requirements.txt -r plugins/self-learning/tools/python/requirements.txt
Install runtime dependencies used by Python tools.
git config core.hooksPath .githooks
Enable repo hooks (required for contributor checks).
./plugins/code/scripts/install-dependencies.sh
Install system/Python dependencies used by the code and self-learning toolchain.
ruff check .
Lint repository Python-style issues.
pyright
Run static type checks.
pytest plugins/
Run all test modules (e.g., test_amend_state.py, test_code_review_helpers.py).

Coding Style & Naming Conventions

Python: 4-space indentation, explicit type annotations for public APIs.
Test files use test_<name>.py; functions use snake_case.
Plugin artifacts are explicit and frontmatter-driven (agents, commands, skills definitions in Markdown).
Use existing conventions in each plugin; avoid changing naming style in adjacent files (for example, slash command names and agent IDs remain kebab-case, e.g. code-review).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
