co-evolution: Instructions file for Codex

AGENTS.md

co-evolution AGENTS.md is an instructions file for Codex, OpenCode from alanshurafa/co-evolution. It costs 2,799 tokens per session, scanned A, original, MIT.

Repository instructions for co-evolution, a project where AI agents iteratively improve documents using shared markers. The markers [CONTESTED] and [CLARIFY] record disagreements and unclear passages for later resolution.

In plain words
What is it for?
Use it when editing documents in the co-evolution repository, especially when reading, adding, resolving, or removing [CONTESTED] and [CLARIFY] markers.
Why use it?
It gives agents a shared process for handling disagreements and ambiguity, while requiring those markers to be resolved as the document is refined.

Instructions file for CodexOpenCode

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

This is alanshurafa/co-evolution's own configuration. It tells Codex and OpenCode how to work on co-evolution 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 co-evolution 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

co-evolution 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.

How it starts

The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.

For agents reading this repo

This repo implements the Bounce Protocol — a convention for structured iterative refinement between AI agents using in-document markers. If you are an agent invoked against documents in this repo, you should know how to read and emit these markers.

The two markers

  • [CONTESTED] — appears on its own line below text you disagree with. The note states the disagreement and proposes a concrete alternative. If you see one in a document you are editing, either resolve it (delete it after applying its alternative or rebutting it) or leave it for the next agent.
  • [CLARIFY] — appears on its own line below ambiguous text. The note offers two interpretations or asks a question with a finite answer space. If you can disambiguate, do so and delete the marker.

Both markers auto-expire after 2 passes: on the final pass of any bounce, you must resolve every remaining marker and may not introduce new ones. This rule guarantees convergence.

Full spec: BOUNCE-PROTOCOL.md. Reference implementation: agent-bouncer/.

How to interact with this repo

  • If you are invoked via /co-evolution or bash co-evolve-bouncer.sh, you are in the general-purpose co-evolution workflow for questions, drafts, plans, specs, arguments, and markdown refinement
  • If you are invoked via /dev-review (Claude Code) or bash dev-review/codex/dev-review.sh (Codex), you are inside the bounce pipeline — your role (reviewer / composer) and pass number are passed to you in the prompt template
  • If you are invoked via /codex-build, you are orchestrating a detached Codex build: the session plans and reviews, Codex executes in the background under --preset codex-build, and the session is woken at gates (see skills/codex-build/)
  • If you are orchestrating via --preset claude-build, Codex plans and reviews while Claude executes the build synchronously; this path hard-requires claude CLI auth because Claude is the executor (see dev-review/codex/claude-build.md)
  • If you are invoked via bash agent-bouncer/agent-bouncer.sh <doc>, you are bouncing a single markdown document — same protocol applies
  • If you are exploring the repo directly without an explicit role, treat the protocol section above as orientation, then read the project-context sections below for structure and conventions

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.
