turbo-flow: Instructions file for Codex

AGENTS.md

turbo-flow AGENTS.md is an instructions file for Codex, OpenCode from marcuspat/turbo-flow. It costs 765 tokens per session, scanned A, original, MIT.

A repository instruction file for Turbo Flow, a small set of scripts and rules for governing AI-written code. Its main rule requires a different model family to review each change, while a human makes the final merge decision.

In plain words
What is it for?
Use it to guide work in the Turbo Flow repository, run its review gate on pull requests or branches, and locate its worktree, secrets, documentation, and automation tools.
Why use it?
It gives coding agents and contributors one shared set of working rules instead of separate instructions for each tool. The review gate helps catch problems before a change is merged.

Instructions file for CodexOpenCode

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

This is marcuspat/turbo-flow's own configuration. It tells Codex and OpenCode how to work on turbo-flow 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 turbo-flow 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

turbo-flow 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 today.

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 — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Turbo Flow

Turbo Flow is rig-lite: a portable governance kit for AI-written code. Bash plus this file — no harness is bundled, no new dependencies. It works with whatever coding agents you already have.

This file is the source of truth for every harness. CLAUDE.md is a symlink to it; Codex and ZCode read it natively. Do not fork instructions per tool.

The one rule that matters

Every change is reviewed read-only by a model from a different family than the one that wrote it, and humans hold the merge button. Enforce it with the gate:

rig-lite/gate.sh --pr <n> --builder <cli>    # gate a GitHub PR, verdict posted as a comment
# verdicts are pinned to the head they gated — new commits = ungated again.
# past GATE_ROUND_CAP (default 3) rounds the gate exits 4: the continue/park
# fork is the human's call (GATE_FORCE=1 overrides consciously).
rig-lite/gate.sh --base main --builder <cli> # branch mode on a working tree

The full law set lives in rig-lite/constitution.md — pair it with the gate so the laws have teeth.

Repo map

Path What it is
rig-lite/ the kit: gate, worktrees, secrets, digest, token dashboard, memory pattern, spec templates, automation prompts, self-test
demo/ the recorded demo + its recorder + auth-guard (refuses to record logged-in sessions)
.devcontainer/ kit container: postCreate runs the self-test, installs tmux, wires the boot hook
workspace.sh the 5-window tmux rig: claude · claude+ruflo · codex · tokens dashboard · shell

Working in this repo

Use tf (one command for everything — installed by init-repo.sh to ~/.local/bin):

  • tf gate --builder <cli> — gate the current branch (vs main; reviewer ≠ builder's family)
  • tf test — the fail-closed self-test suite
  • tf secrets set/get/rm/list — encrypted secrets (names only when listing)
  • tf wt <name> — isolated worktree per parallel writer
  • tf digest — fleet health report
  • tf tokens --watch — live token dashboard
  • tf status — everything at a glance (repo, gate stats, session, tree)
  • tf init — install the kit into any repo
  • tf protect — enable branch protection (Law 2 enforcement)

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.
