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 | $0.01043 | $0.01043 |
| Opus 5 | $0.00522 | $0.00522 |
| Sonnet 5 | $0.00209 | $0.00209 |
| Haiku 4.5 | $0.00104 | $0.00104 |
Grade A, and why
codex-agent-mem AGENTS.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 5d 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS
This repository is intentionally optimized for MCP-compatible AI agents, coding workflows, deep-research tools, and maintainers who need a fast map of what exists today.
Public name vs import name
- Public repository name:
codex-agent-mem - Python package import name:
codex_agent_mem - CLI commands use the public name with hyphens, for example
codex-agent-mem-smoke
What this project is
- A portable, local-first MCP memory layer for agent continuity across MCP-compatible runtimes
- Current durable store: local SQLite
- Current retrieval surface: MCP stdio
- Current capture path: local agent turn ingestion, including Codex
notifyonagent-turn-complete - Current inspection surface: local FastAPI UI at
/ui - Current continuity surface: generated
AGENTS.mdworking-memory block when compression is favorable - Current extraction strategy: heuristic extraction of session summaries, user requests, objectives, decisions, constraints, pending/completed work, blockers, DoD items, and completion claims
Working rules for agents
- Preserve the local-first MCP core.
- Do not use an operational maintainer database for tests; use temporary databases.
- Keep hosted/web bridge experiments out of the public core unless the repository scope changes explicitly.
- Keep compatibility and token-savings claims tied to reproducible evidence.
- Keep the six README files equivalent in content across languages.
- For broad/container project keys, prefer
mem_bootstrap_contextormem_scope_resolvebefore loadingmem_context_pack(project_key). A project-wide pack may remain available, but it must not be treated as the active thread when candidate lanes are ambiguous. - Do not tag, publish, or release from a dirty tree.

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.

codex-agent-mem AGENTS.md is an instructions file published in the GitHub repository MarceloCaporale/codex-agent-mem (37 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 1,043 tokens to every session, about $0.0052 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.
