repomemory: Instructions file for Codex

AGENTS.md

repomemory AGENTS.md is an instructions file for Codex, OpenCode from DanielGuru/repomemory. It costs 2,058 tokens per session, scanned A, original, MIT.

Instructions for working on repomemory, a TypeScript command-line tool and MCP server that stores searchable project knowledge for coding agents. It keeps information such as decisions, facts, regressions, preferences, and session logs in a .context directory.

In plain words
What is it for?
Use it when building, testing, or changing repomemory, including its CLI commands, repository analysis, memory search, session capture, and Git-history synchronization.
Why use it?
It helps an agent preserve useful repository knowledge across sessions instead of repeatedly rediscovering the same project details.

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

repomemory 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.

repomemory — Instructions for AI Coding Agents

This file is for Codex, Copilot Workspace, Devin, and any other AI agent working on this codebase.

Project Overview

repomemory is a CLI tool + MCP server that gives AI coding agents persistent memory for repositories. It creates a .context/ directory with structured knowledge (facts, decisions, regressions, preferences, session logs) that agents can search, write to, and delete from. Features hybrid keyword + semantic search, auto-session capture, intelligent category routing, auto-purge detection, and global developer context (~/.repomemory/global/) that follows you across all repos.

Language: TypeScript (ESM, strict mode) Runtime: Node.js 20+ Package manager: npm Build: npm run build (runs tsc + shebang injection via scripts/build.js) Test: npm test (vitest, 163 tests)

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.
