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.

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 | $0.00081 | $0.02470 |
| Opus 5 | $0.00041 | $0.01235 |
| Sonnet 5 | $0.00016 | $0.00494 |
| Haiku 4.5 | $0.00008 | $0.00247 |
Grade A, and why
codebase-documenter scanned grade A with 1 finding 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Codebase Documenter
Overview
This skill enables creating comprehensive, beginner-friendly documentation for codebases. It provides structured templates and best practices for writing READMEs, architecture guides, code comments, and API documentation that help new users quickly understand and contribute to projects.
Core Principles for Beginner-Friendly Documentation
When documenting code for new users, follow these fundamental principles:
- Start with the "Why" - Explain the purpose before diving into implementation details
- Use Progressive Disclosure - Present information in layers from simple to complex
- Provide Context - Explain not just what the code does, but why it exists
- Include Examples - Show concrete usage examples for every concept
- Assume No Prior Knowledge - Define terms and avoid jargon when possible
- Visual Aids - Use diagrams, flowcharts, and file tree structures
- Quick Wins - Help users get something running within 5 minutes
Documentation Types and When to Use Them
1. README Documentation
When to create: For project root directories, major feature modules, or standalone components.
Structure to follow:
# Project Name
## What This Does
[1-2 sentence plain-English explanation]
## Quick Start
[Get users running the project in < 5 minutes]
## Project Structure
[Visual file tree with explanations]
## Key Concepts
[Core concepts users need to understand]
## Common Tasks
[Step-by-step guides for frequent operations]
## Troubleshooting
[Common issues and solutions]
Best practices:
- Lead with the project's value proposition
- Include setup instructions that actually work (test them!)
- Provide a visual overview of the project structure
- Link to deeper documentation for advanced topics
- Keep the root README focused on getting started
2. Architecture Documentation
When to create: For projects with multiple modules, complex data flows, or non-obvious design decisions.

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.

codebase-documenter is a skill published in the GitHub repository ailabs-393/ai-labs-claude-skills (444 stars, last pushed 10mo ago), licensed MIT. It adds 81 tokens to every session and 2,470 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
