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 | $0.02327 | $0.02327 |
| Opus 5 | $0.01163 | $0.01163 |
| Sonnet 5 | $0.00465 | $0.00465 |
| Haiku 4.5 | $0.00233 | $0.00233 |
Grade A, and why
claude-code-auto-memory 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.
How it starts
The opening of the file, as written. The whole thing — 171 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.
Overview
claude-code-auto-memory - A Claude Code plugin that automatically maintains CLAUDE.md files (or AGENTS.md for multi-agent repos) as codebases evolve. Tracks file changes via hooks, spawns agents to update memory, and provides skills for codebase analysis.
Key features:
- Real-time file tracking via PostToolUse hooks
- Stop hook integration to trigger memory updates
- Codebase analyzer skill for initial setup
- Memory processor skill for ongoing updates
- AGENTS.md support for multi-agent workflows (OpenAI Codex, Gemini, etc.)

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-auto-memory CLAUDE.md is an instructions file published in the GitHub repository severity1/claude-code-auto-memory (157 stars, last pushed 4mo ago), licensed MIT. It adds 2,327 tokens to every session, about $0.0116 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.
