cartograph: Instructions file for Codex

AGENTS.md

cartograph AGENTS.md is an instructions file for Codex, OpenCode from adder-factory/cartograph. It costs 1,670 tokens per session, scanned A, original, MIT.

Repository instructions for using Cartograph, a code-intelligence service that maps relationships in a codebase and provides them to coding agents.

In plain words
What is it for?
Use them to explore a repository, find callers and references, assess change impact, select affected tests, and review current or uncommitted changes.
Why use it?
They give the agent a checked process for installing Cartograph, choosing database ownership, and avoiding decisions based on an outdated code index.

Instructions file for CodexOpenCode

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

This is adder-factory/cartograph's own configuration. It tells Codex and OpenCode how to work on cartograph 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 cartograph 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

cartograph 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 6d 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 — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — install and use Cartograph v3 from an AI coding agent

Cartograph is this workspace's native code-intelligence MCP server. These instructions are deliberately mechanical: execute a step, verify its result, then continue.

Working on the Cartograph repository itself? Read AGENTS.local.md before changing code. It contains the private development conventions, architecture gates, Sonar workflow, reviewer step, and release procedure. A fresh public clone does not contain that git-ignored file.

Existing project rule

If .cartograph/ or a project-local Cartograph MCP registration exists, use Cartograph for relationship-aware exploration:

  • cartograph context for broad coding-task evidence;
  • cartograph find for exact name/path/reference or BM25 lookup;
  • cartograph graph for callers, callees, and reverse impact;
  • cartograph affected for test selection;
  • cartograph review for compare-to-ref and dirty-worktree evidence;
  • cartograph status before relying on the index.

If the index is stale, run cartograph index <project> or call the MCP cartograph_admin index action. Do not present stale evidence as current.

If the project has no Cartograph setup, ask:

I notice this project does not have Cartograph initialized. Would you like me to run cartograph admin init -i to build a code knowledge graph?

Architecture and hard requirements

This checkout replaces PostgreSQL completely with per-project RocksDB 11.8.1. Version v3.0.0 ships this native backend. Existing v2 installations need the v3 executable, a source rebuild, and host restart before using RocksDB. Read AGENTS.local.md for development gates. Its historical PostgreSQL-specific requirements are superseded by this authorized native migration.

Cartograph remains a native Rust executable with deterministic extraction, generation provenance, exact/code-aware BM25/graph retrieval, and optional model-scoped semantic evidence. No SQL runtime, PostgreSQL fallback, Docker bootstrap, SQLite path, or SQL query tool remains.

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.
