engraphis: Instructions file for Codex

AGENTS.md

engraphis AGENTS.md is an instructions file for Codex, OpenCode from Coding-Dev-Tools/engraphis. It costs 4,947 tokens per session, scanned A, original, Apache-2.0.

The operating manual for Engraphis, a local-first memory engine for AI agents. It explains the current and older implementations, which are two separate codebases in the same package.

In plain words
What is it for?
It guides changes to memory storage, search and recall, backends, tests, evaluation code, and migration scripts.
Why use it?
It prevents developers from editing the legacy implementation by mistake and explains how the current memory system is organized.

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

This is Coding-Dev-Tools/engraphis's own configuration. It tells Codex and OpenCode how to work on engraphis 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 engraphis 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

engraphis 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 — 305 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Engraphis

Engraphis is a local-first, open AI memory engine for agents — Ebbinghaus decay, interaction-aware reinforcement, bi-temporal facts, hybrid recall, and a native workspace → repo → session → memory hierarchy. Python 3.9+ for the core (Python 3.10+ for the server/MCP stack), FastAPI, SQLite, and local embeddings; the external LLM is optional and pluggable.

This is the canonical operating manual for any AI agent working in this repo. CLAUDE.md imports it. Read §0 before editing anything.

Internal subagent delegation

When parallel delegation is appropriate for ChatGPT/Codex tasks, use exactly four bounded subagents inside the current task and chat. Keep delegation at one level: workers return bounded results and the parent performs the sole integration. Subagents must never be sent to Orca, Orca orchestration, or separate user-visible threads. Before finalizing, verify that all four workers returned and that no forbidden routing or descendant delegation occurred.


0. Read this first — two architectures live in one package

There are two parallel codebases under engraphis/. Confusing them is the single most common mistake here.

v2 — current architecture (build here) v1 — legacy reference server
Status Primary scoped, bi-temporal, interface-driven implementation. Compatibility/reference implementation with flat namespaces.
Model Scoped + bi-temporal + typed; interface-driven. Single flat namespace string per memory.
Code engraphis/core/, engraphis/backends/, eval/, tests/, scripts/migrate_to_v2.py engraphis/app.py, config.py, models.py, routes/, stores/, engines/, llm/, static/
Data new v2 schema (SCHEMA_VERSION = 18) engraphis_v1.db
Entry engraphis.MemoryEngine.create() / engraphis.create_memory_engine() → engraphis/factory.py → core/engine.py Internal reference only; never a public launcher

Rule: build new capability on v2 (core/ + backends/) behind the interfaces. Only touch the v1 server for compatibility fixes or to keep the reference running. When a task is ambiguous, decide which side it belongs to before editing.

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.
