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 | $0.00668 | $0.00668 |
| Opus 5.5 | $0.00267 | $0.00267 |
| Sonnet 5.5 | $0.00134 | $0.00134 |
| Haiku 4.5 | $0.00067 | $0.00067 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.mdwith 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.

better-code CLAUDE.md is an instructions file published in the GitHub repository hculap/better-code (2 stars, last pushed 8d ago), licensed MIT.
