better-code CLAUDE.md

A set of instructions for working on Better Code, a collection of Claude Code plugins in one repository, called a monorepo.

In plain words
What is it for?
Developing or testing the repository's plugins, including tools for test-driven development (TDD), performance analysis, README files, documentation, and code standards.
Why use it?
It explains the repository layout, development commands, plugin structure, and how to test or install its plugins, so contributors do not have to infer these details.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Security

Grade A, and why

better-code CLAUDE.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 yesterday.

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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a monorepo of Claude Code plugins focused on code quality and developer productivity. The marketplace name is better-code and contains 5 plugins: tdd-dev, n1-optimizer, readme-writer, doc-master, and code-standards.

Development Commands

# Test a plugin locally
claude --plugin-dir plugins/<plugin-name>

# Install from marketplace (for users)
/plugin marketplace add hculap/better-code
/plugin install <plugin-name>

Repository Structure

.claude-plugin/marketplace.json   # Plugin registry for marketplace
plugins/
  tdd-dev/                        # TDD enforcement with hooks
  n1-optimizer/                   # Parallel performance analysis (4 agents)
  readme-writer/                  # README generation/auditing
  doc-master/                     # Documentation toolkit (9 agents)
  code-standards/                 # Code quality enforcement

Plugin Architecture

Each plugin follows this structure:

plugin-name/
├── .claude-plugin/plugin.json    # Manifest: name, version, description, agents array
├── agents/*.md                   # Autonomous agents with YAML frontmatter
├── commands/*.md                 # Slash commands with YAML frontmatter
├── skills/<topic>/SKILL.md       # Knowledge skills with references/ and examples/
├── hooks/hooks.json              # (optional) Hook configuration
└── README.md

Key File Conventions

  • Agent frontmatter: name, description (with <example> blocks), model, color, tools
  • Command frontmatter: description, allowed-tools, argument-hint
  • Skill frontmatter: name, description (trigger phrases), version
  • Use lowercase with hyphens for directories/files (except SKILL.md)
  • Settings files: .claude/plugin-name.local.md with YAML frontmatter

Plugin Patterns

tdd-dev: Uses hooks for enforcement. State stored in .claude/.tdd-mode-active. PreToolUse hooks intercept Write/Edit based on strictness level.

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.
