coding-agent-orchestration: Instructions file for Codex

AGENTS.md

coding-agent-orchestration AGENTS.md is an instructions file for Codex, OpenCode from brifl/coding-agent-orchestration. It costs 2,470 tokens per session, scanned A, original, MIT.

Repository instructions that define how a coding agent should work in the coding-agent-orchestration project. The project stores workflow state, plans, and history in a .vibe directory, with a stated order for resolving conflicts.

In plain words
What is it for?
They guide session startup, instruction precedence, and completing one coherent unit of work at a time while following the repository's state, plan, and history files.
Why use it?
They give the agent a reliable starting reading order and explain which files contain current truth, planned work, and background history. This prevents decisions based only on assumptions or stale notes.

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

This is brifl/coding-agent-orchestration's own configuration. It tells Codex and OpenCode how to work on coding-agent-orchestration itself, so it is not a mod to install elsewhere.

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

coding-agent-orchestration 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.

AGENTS.md — Execution Contract (Repo Baseline)

Purpose

This file defines the working contract for coding agents and humans collaborating in this repository.

  • This repo uses project-local workflow files stored under .vibe/.
  • The agent must follow the precedence order and stop conditions below.
  • This baseline is intended to be copied into target repos and may drift per project.

Authoritative files and precedence

When instructions conflict, follow this order:

  1. User instructions in the current chat
  2. This file: AGENTS.md
  3. .vibe/STATE.md (current truth: what we are doing now)
  4. .vibe/PLAN.md (checkpoint backlog and acceptance criteria)
  5. .vibe/HISTORY.md (non-authoritative rollups, context only)
  6. Repository source code and tests
  7. Anything else (including assumptions)

Required behavior

Read order at the start of a session

At the start of any new session (or when context is unclear), the agent must:

  1. Read AGENTS.md (optional if already read this session)
  2. Read .vibe/STATE.md
  3. Read .vibe/PLAN.md
  4. Optionally read .vibe/HISTORY.md if needed

Work granularity

  • Do one coherent unit of work at a time (typically one checkpoint step).
  • Prefer small, reviewable diffs.
  • When ambiguity affects correctness, ask 1–2 clarifying questions max as issues in .vibe/STATE.md, then stop.

Deferral for throughput

  • If an issue, checkpoint, or stage is blocked but later independent work can safely proceed, mark it [DEFERRED] and move on instead of stopping the project.
  • Add a short reason and unblock/revisit condition near the deferred item. Waiting on human feedback is a legitimate deferral reason.
  • Do not defer work that a later item depends on unless that later item is also deferred or redesigned; deferral is for preserving momentum, not hiding shaky foundations.
  • Revisit [DEFERRED] items during stage design and consolidation. If the unblock condition is now true, reactivate the item or fold it into the next executable checkpoint.

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.
