repo-template: Instructions file for Codex

AGENTS.md

repo-template AGENTS.md is an instructions file for Codex, OpenCode from p-to-q/repo-template. It costs 758 tokens per session, scanned A, original, Apache-2.0.

A repository guide for coding agents and developers. A repository is the project folder containing its code, documentation, tests, and configuration.

In plain words
What is it for?
It is for explaining the project's structure, conventions, validation expectations, contribution process, and how to handle unfinished work.
Why use it?
It gives agents a shared reading order and working rules, reducing hidden decisions, unnecessary changes, and unsupported claims.

Instructions file for CodexOpenCode

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

This is p-to-q/repo-template's own configuration. It tells Codex and OpenCode how to work on repo-template 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 repo-template 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

repo-template 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 9d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This file is the long-form operating guide for coding agents and humans who delegate work to agents.

It is adapted from Wittgenstein's AGENTS.md and cross-filled with repository-first discipline from Jah-yee/cursor-rules. Project-specific codec doctrine has been replaced by a general repository discipline contract.

Operating thesis

The repository is the source of truth. Prompts can start work, but durable contracts live in code, docs, tests, issues, PRs, and decision records.

An agent should optimize for:

  1. small, reviewable changes;
  2. explicit validation;
  3. no hidden architectural decisions;
  4. no claims without receipts;
  5. useful handoff notes when work stalls;
  6. route deletion when a template lane is not called.

Read order

Before editing, read only the smallest relevant set:

  1. README.md — project route and status.
  2. docs/project-scale.md — current profile.
  3. docs/router.md — what files/routes are active.
  4. docs/contributor-map.md — where things live.
  5. docs/engineering-discipline.md — change discipline.
  6. docs/agent-rules.md — optional stack/Cursor rules.
  7. CONTRIBUTING.md — branch and PR rules.
  8. WORKFLOW.md — issue/agent dispatch rules when agent orchestration is in scope.
  9. Any linked docs/handoff/*.md or issue body.
  10. ADR/RFC/brief only if the task touches a decision-bearing surface.

Non-negotiables

  • Do not invent context that is not in the repo, issue, PR, or handoff brief.
  • Do not silently change public API, license, release, security, workflow, agent contract, or label semantics.
  • Do not claim tests passed unless you ran them.
  • Do not mix unrelated refactors into a feature or fix.
  • Do not use generated code as a substitute for a design decision.
  • Do not add new machinery to signal seriousness.
  • When blocked, leave a precise handoff note with files read, changes made, validation run, and next decision needed.

Decision-bearing surfaces

Treat these as requiring maintainer attention and, for strict projects, ADR/RFC linkage:

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.
