nuzo-memory: Instructions file for Codex

AGENTS.md

nuzo-memory AGENTS.md is an instructions file for Codex, OpenCode from fabionfsc/nuzo-memory. It costs 1,121 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for Nuzo, a local-first memory system for AI coding assistants and other MCP-compatible agents. Local-first means the main data stays on the user’s machine, and auditable means changes can be inspected.

In plain words
What is it for?
Guiding work on Nuzo’s core packages, command-line tool, MCP server, host plugins, documentation, and local setup.
Why use it?
They give contributors a starting point and architectural boundaries while warning them not to expose secrets or private memory data.

Instructions file for CodexOpenCode

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

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

nuzo-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 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.

Agent Instructions

This repository is the design, implementation, and documentation home for Nuzo.

Nuzo is a local-first, auditable memory layer for Codex, Claude Code, and MCP-compatible AI agents. Version 1.2.0 is the current public release.

Start Here

Read these first:

  1. README.md
  2. CONTRIBUTING.md
  3. docs/getting-started/index.md
  4. docs/operations/roadmap.md
  5. docs/architecture/overview.md
  6. docs/architecture/boundaries.md
  7. docs/spec/tools.md
  8. docs/spec/memory-model.md
  9. docs/spec/capture-suggestions.md

Use docs in docs/ as the source of detail. Keep root files short entry points.

Local Notes

If AGENTS.local.md exists at the repository root, read it after this file.

AGENTS.local.md is for machine-local operator preferences, temporary environment notes, and non-public workflow guidance. It is ignored by Git and must not be committed.

Do not put secrets, real memory exports, credentials, tokens, private user data, or personal operator notes in public docs, issues, examples, or tests.

Architecture Rules

  • Business logic belongs in packages/core.
  • CLI, MCP server, and host plugins must call core use cases instead of duplicating behavior.
  • MCP tool schemas are public contracts. Update docs/spec/tools.md before or alongside tool contract changes.
  • Host plugins should remain thin wrappers around the MCP server.
  • Storage starts with SQLite and SQLite FTS.
  • Optional local embeddings shipped; sync, encryption, and UI remain outside the final upstream release.
  • Do not introduce telemetry, network calls, remote embeddings, or silent inferred writes by default.
  • Inferred memories are drafts until the user confirms them.

Package Direction

The intended package direction is:

core -> cli/mcp-server -> memory package -> host plugins

Most users install @nuzo/memory. MCP hosts and generated host plugin artifacts resolve @nuzo/memory. Library-level integrations use @nuzo/memory-core. The official MCP Registry resolves the single-entrypoint @nuzo/memory-mcp distribution starting with 1.1.0; it reuses the shared MCP server build and is not a second implementation.

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.
