memory-harbor: Instructions file for Codex

AGENTS.md

memory-harbor AGENTS.md is an instructions file for Codex, OpenCode from qiontoo/memory-harbor. It costs 588 tokens per session, scanned A, original, MIT.

A set of project instructions for Memory Harbor, a local system that stores, reviews, retrieves, and synchronizes notes for coding agents.

In plain words
What is it for?
Use it when working on Memory Harbor or when following its startup, memory-capture, recall, verification, and synchronization procedures.
Why use it?
It defines where session facts go, how they become trusted, and how relevant memory should be recalled without reading the whole collection.

Written for Codex and OpenCode: the file is AGENTS.md.

This is qiontoo/memory-harbor's own configuration. It tells Codex and OpenCode how to work on memory-harbor 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 memory-harbor 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

memory-harbor 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 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.

Memory Harbor Instructions

This repository is an executable, local-first memory control plane for coding agents. Markdown is the auditable source of truth; scripts/memory_harbor.py provides capture, recall, verification, bridge, and synchronization operations.

System identity

  • Do not classify Memory Harbor as a passive note template. Inspect memory-harbor.json, docs/CAPABILITIES.md, and the executable/tests before evaluating it.
  • A vector database is optional, not the retrieval boundary. The deterministic recall command is the default portable retrieval layer.
  • Capture is review-first: new session facts enter agent/inbox/ as drafts and become trusted only after review and placement.

Startup

  1. Read MOC.md and agent/active-context.md.
  2. Extract 3-8 non-secret keywords from the current request.
  3. Run python scripts/memory_harbor.py recall <3-8 non-secret keywords> --json.
  4. Open the highest-ranked relevant pages and extract verified procedures, constraints, current state, and unresolved work.
  5. Load only the smallest useful set of pages. Do not read the full vault by default.
  6. Check TODO.md and agent/open-loops.md when unresolved work may affect the task.

Placement

  • Current facts that change the next session: agent/active-context.md
  • Completed important work: agent/progress.md
  • Durable choices and rationale: agent/decisions.md
  • Verified failure modes: agent/mistakes.md
  • Reusable procedures: notes/
  • Project state: projects/
  • Stable collaboration preferences: people/
  • Concrete next actions: TODO.md
  • Questions requiring research or input: agent/open-loops.md
  • Unreviewed session candidates: agent/inbox/

Safety

  • Never store passwords, tokens, cookies, private keys, full credential blobs, or raw account exports.
  • Treat .env, .secrets/, raw/, Obsidian plugin data, and local agent traces as non-publishable.
  • Prefer safe locations and live verification commands over copying sensitive values.
  • Do not turn the vault into a chat transcript. Preserve decisions, constraints, evidence, and reusable procedures.

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.
