Agentic-Memory: Instructions file for Codex

AGENTS.md

Agentic-Memory AGENTS.md is an instructions file for Codex, OpenCode from ArkaAiAdmin/Agentic-Memory. It costs 5,809 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for maintaining the Agentic-Memory codebase. They explain its structure, the rules agents must follow, and the expected session workflow.

In plain words
What is it for?
Use them when working on Agentic-Memory, especially for starting sessions, searching and saving project memory, and following maintenance rules.
Why use it?
They reduce confusion about which documents, memory actions, checks, and rules apply during a coding session.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions subagents; mentions AGENTS.md; mentions OpenCode.

This is ArkaAiAdmin/Agentic-Memory's own configuration. It tells Codex and OpenCode how to work on Agentic-Memory itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Agentic-Memory configures →

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.

Security

Grade A, and why

Agentic-Memory 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 1mo 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 — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — agentic-memory (Maintainer Edition)

You maintain the agentic-memory codebase. All commands run from the repo root.

If you are an agent using the system (not maintaining it): read AGENT_CONTRACT.md (5 rules) + docs/AGENT_QUICKSTART.md. Stop there.


System at a Glance

Live counts (schema version, tool surface, cron/hooks, test files, LOC) live in docs/_meta.json (machine-enforced by verify_doc_meta.py). Architecture: docs/architecture.md. MCP tool surface: docs/MCP_SURFACE.md. For agents using the system: AGENT_QUICKSTART.md.


Session Protocol

# When Action
1 Every session start agentic-memory_memory_session_start(query="<subsystem>") — anchors a real DB-backed session (writes .current_session.json with the authoritative id) and returns the briefing. The harness hook does this automatically when wired; the verb is the fallback and is self-sufficient.
2 Before any task agentic-memory_memory_search(query="<topic>")
3 After bug/decision fix agentic-memory_memory_save(category="lessons" or "decisions")
4 After test/index/cron op agentic-memory_memory_advanced(operation="auto_save_status") — only when cron is down or immediate results are needed (Rule 21)
5 Before ending session agentic-memory_memory_save(category="sessions"), then memory_session_end(summary=...). No session handle needed — end falls back to the state file, then to the most recent active session for this agent; with nothing active it returns a structured no-op instead of erroring.

Minimum every session: #1 + #5. Save context-rich projects notes (importance=4) at milestones — useful weeks later, not log lines.

Session persistence requires [session_memory] enabled = true (on since 2026-08-22). Skill extraction vetoes eval/test residue ids (skill_extractor.is_junk_memory_id) and strips YAML frontmatter; sweep with scripts/purge_junk_skills.py if junk ever returns.

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.
