gnosys: Instructions file for Codex

AGENTS.md

gnosys AGENTS.md is an instructions file for Codex, OpenCode from proticom/gnosys. It costs 1,213 tokens per session, scanned A, original, MIT.

A set of instructions for working on Gnosys, an open-source system that stores an AI agent’s long-term memories in a SQLite database and provides them through tools and a command-line program.

In plain words
What is it for?
Use it when changing Gnosys, checking its build and tests, or working with its memory database, tool server, command-line interface, and search system.
Why use it?
It gives coding agents the project’s architecture, rules, and commands so they can work consistently without rebuilding that context each session.

This is proticom/gnosys's own configuration. It tells Codex and OpenCode how to work on gnosys 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 gnosys 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

gnosys 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 15d 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.

AGENTS.md

Instructions for AI agents working in the Gnosys codebase.

What is Gnosys

Gnosys is an open-source persistent memory system for AI agents. It stores structured memories in a central SQLite database and exposes them via MCP (Model Context Protocol) tools and a CLI. Agents use Gnosys to remember decisions, architecture, project status, and context across sessions.

Quick Reference

npm run build          # tsc -> dist/ (tsconfig.build.json — excludes tests)
npm test               # vitest run (1700+ tests, all should pass)
npm run typecheck      # tsc --noEmit (covers tests too — CI-gated)
npm run lint           # biome (zero warnings — CI-gated)
npm run knip           # dead code / unused exports (zero findings — CI-gated)

Architecture

  • Entry points: src/index.ts (MCP server, 50+ tools), src/cli.ts (CLI, 30+ commands)
  • DB-only: Central SQLite at ~/.gnosys/gnosys.db is the sole source of truth. No markdown files.
  • Search: FTS5 keyword -> semantic embeddings -> hybrid RRF -> federated cross-project
  • Web KB: gnosys/web subpath export for serverless chatbots (zero native deps at runtime)
  • Portfolio: src/lib/portfolio.ts + portfolioHtml.ts for cross-project status dashboard
  • Multi-machine sync (v5.3.0): src/lib/remote.ts syncs local cache with remote (NAS) DB

Key Rules

  1. DB-first lookups: When resolving a memory by ID (e.g. road-007), always check centralDb.getMemory(id) before falling back to the legacy file resolver.
  2. No markdown writes: All memory writes go to SQLite only. Markdown is generated on-demand via gnosys export.
  3. TypeScript strict: strict: true in tsconfig. Fix all type errors before committing.
  4. Test before commit: Run npm test — the full suite must pass (1700+ tests in src/test/). CI also gates tsc --noEmit, biome lint, and knip.
  5. Path quoting: The project may live in a path with spaces (iCloud). Always quote paths in shell commands.
  6. Web subpath isolation: src/lib/staticSearch.ts must not import (only import type) from modules that depend on node:sqlite or any native addon.
  7. CLI-first, MCP-second: New features are CLI commands first; MCP tools are thin wrappers around CLI logic.

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.
