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.
npx agentmods add instructions/codenamev/claude_memory/claude-mdgit clone --depth 1 https://github.com/codenamev/claude_memoryWhat 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 | $0.06684 | $0.06684 |
| Opus 5 | $0.03342 | $0.03342 |
| Sonnet 5 | $0.01337 | $0.01337 |
| Haiku 4.5 | $0.00668 | $0.00668 |
Grade A, and why
claude_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 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.
How it starts
The opening of the file, as written. The whole thing — 535 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
ClaudeMemory is a Ruby gem that provides long-term, self-managed memory for Claude Code using hooks, MCP tools, and output styles. It ingests transcripts, distills them into facts with provenance, resolves contradictions, and publishes curated snapshots.
Key dependencies:
- Ruby 3.2.0+
- Sequel (~> 5.0) for database access
- Extralite (~> 2.14) for high-performance SQLite storage
Working with This Codebase
Check memory before exploring code. Use memory.recall, memory.decisions, memory.architecture, or memory.conventions to find existing knowledge before reading files.
Public API contract: docs/api_stability.md is the authoritative stable-surface list (CLI, MCP, hooks, Ruby API, schema, predicate vocabulary). When changing any of those surfaces, update the doc in the same commit; if it's a soft-rename, wire ClaudeMemory::Deprecations.warn.
Audit memory health: run claude-memory audit (or /audit-memory for an interactive walkthrough) to surface inconsistencies, regressions, and optimization opportunities. See docs/audit_runbook.md for per-check rationale and remediation steps.
Git Usage & Best Practices
- Before each commit, apply the quality-review skill
- Iteratively commit related changes with their tests
Development Commands
Setup
bin/setup # Install dependencies
Testing
bundle exec rspec # Run unit/integration tests (~76s)
bundle exec rspec spec/claude_memory/cli_spec.rb # Run single test file
bundle exec rspec spec/claude_memory/cli_spec.rb:42 # Run specific test by line number
bundle exec rake spec # Alternative test command
bundle exec rake # Run tests + Standard linter (default task)
Note: Benchmarks and evals are excluded from the default rspec run via .rspec. See the Evals and Benchmarks sections for running those separately.
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_memory CLAUDE.md is an instructions file published in the GitHub repository codenamev/claude_memory (24 stars, last pushed 1mo ago), licensed MIT. It adds 6,684 tokens to every session, about $0.0334 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.
