totem: Instructions file for Codex

AGENTS.md

totem AGENTS.md is an instructions file for Codex, OpenCode from mmnto-ai/totem. It costs 1,233 tokens per session, scanned C, original, Apache-2.0.

A repository guide that defines how coding agents should work in Totem, a toolkit that checks project rules and records derived project information in Git. It includes required steps before searching, planning, coding, and pushing changes.

In plain words
What is it for?
Use it when developing Totem, checking repository health, searching its knowledge base, running its checks, or following its package, TypeScript, and testing conventions.
Why use it?
It reduces architecture mistakes and catches rule violations before changes are shared.

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

This is mmnto-ai/totem's own configuration. It tells Codex and OpenCode how to work on totem 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 totem 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 C, and why

totem AGENTS.md scanned grade C with 1 finding 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Totem: Agent Instructions

Canonical source of truth for how AI coding agents behave in this repository. Following the AGENTS.md convention, mmnto-ai/totem consolidates tool-specific instruction files into this single AGENTS.md; thin per-tool redirect files point each tool here. Team-only instructions for this repository ride a private doctrine package and are never committed here.

What Totem is

Totem is a local-first toolkit that keeps AI-agent work queryable, enforceable, and derivable as plain files in your codebase. Lead with enforcement (totem lint and the gate engine), not recall; derivation (totem status, totem orient) and the queryable index serve it.

Session start

  1. Run totem status for health.
  2. Never guess architecture. Before modifying a core system, run totem search <system>.
  3. Before writing code, call search_knowledge describing what you are changing.
  4. Do not push speculative fixes: run totem lint locally and front-load every check before the first push.
  5. Cold start (no session hook injected orientation): derive it with totem orient, after /signon's seat and assignment-mail steps where that skill is installed.

Working rules

  • Before pushing: your formatter, then totem lint (the enforcement floor), then totem review where configured (advisory lanes, never a merge gate).
  • After a PR merges: totem lesson extract <pr> --yes.
  • Never bypass a quality gate without a ticket. No --no-verify, totem-ignore, eslint-disable, @ts-ignore, skipped tests, or ignore patterns added to pacify CI; a suppression carries a ticket reference.
  • After roughly 15 turns of code changes: run totem status, re-query the knowledge index for the system you are modifying, and state your architectural assumption.
  • Controller, not implementer. Delegate build-and-test cycles to background agents; keep this thread for decisions.

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.
