aitori: Instructions file for Codex

AGENTS.md

aitori AGENTS.md is an instructions file for Codex, OpenCode from truefoundry/aitori. It costs 1,179 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for Aitori, a multi-module codebase whose modules handle configuration, certificates, routing, proxying, and operating-system integration.

In plain words
What is it for?
Finding the right Aitori module, following its build, test, and lint workflow, and preserving rules such as its routing and configuration behavior.
Why use it?
They give coding agents the project's layout, required checks, and contracts that must remain intact while changes are made.

Instructions file for CodexOpenCode

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

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

aitori 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.

Multi-module repo + the CGO rule

Two Go modules:

  • root (github.com/truefoundry/aitori) — the agent. Stays dependency-light.
  • tools/aitori-gateway — its own module; carries the heavier OTel + SQLite deps so they never reach the agent.

Always build and test with CGO_ENABLED=0. A transitive gopsutil dependency (go-m1cpu) crashes at init under cgo on recent Go/macOS. The Makefile sets this for you; if you invoke go directly, set it yourself. The gateway uses the pure-Go modernc.org/sqlite driver for the same reason.

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.
