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.

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 | $0.00351 | $0.00351 |
| Opus 5 | $0.00176 | $0.00176 |
| Sonnet 5 | $0.00070 | $0.00070 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
claude-code-patterns 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 2d 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.
What it actually says
Claude Code Pattern Library
Field-tested techniques for Claude Code, organized into five parts (counts live in README.md). When the user asks about Claude Code workflows, patterns, or best practices, search these files for relevant techniques. Reference techniques by title.

For AI Agents
This repo is designed to be consumed programmatically. To build an implementation plan:
- Read the README for architecture overview and orientation
- Read Part 3 (BUILD-A-KNOWLEDGE-BASE) for the step-by-step builder table
- Read Part 2 (TECHNIQUES) for specific tips relevant to the user's stack
- Produce a sequenced implementation plan with dependencies
- Create a PULSE.md tracker for the adoption project itself (see "Project Pulse Files for Completion Tracking" in Part 2) and update it every session, so each future session resumes exactly where this one stopped
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.

claude-code-patterns CLAUDE.md is an instructions file published in the GitHub repository AaronRoeF/claude-code-patterns (120 stars, last pushed 13d ago), licensed MIT. It adds 351 tokens to every session, about $0.0018 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
