What is claude-code-auto-memory CLAUDE.md?

A Claude Code plugin that maintains CLAUDE.md or AGENTS.md files as a codebase changes. It tracks file changes, analyzes the codebase, and runs memory updates through hooks.

Setting up repository guidance, tracking changes, updating memory files, and supporting multi-agent repositories. It also documents commands for installing dependencies, testing, linting, formatting, and type checking.

It reduces the need to manually keep agent guidance current as files and project structure evolve.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02327	$0.02327
Opus 5.5	$0.00931	$0.00931
Sonnet 5.5	$0.00465	$0.00465
Haiku 4.5	$0.00233	$0.00233

Security

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 2mo 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.

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.
