Manifest AGENTS.md

Manifest AGENTS.md is an instructions file for Codex, OpenCode from iampawan/Manifest. It costs 1,634 tokens per session, scanned A, original, MIT.

A set of instructions for Manifest, a tool that takes a product requirements document from planning through building and launch. It defines checks for whether a requirements document is ready before development planning begins.

In plain words
What is it for?
Use it to score requirements, create tamper-evident hand-offs, verify gate results, and enforce Manifest's required planning checks.
Why use it?
It prevents teams from using hand-written approval results that cannot be verified, and makes the same checks work across different coding tools and continuous-integration systems.

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

Manifest 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Manifest

Manifest takes a PRD from spec → build → launch with quality gates. Version 0.43.0.

Works in any agent. The gates are plain Node, so Codex, Cursor, Gemini CLI, Copilot, Aider, Windsurf, Zed and CI all get identical results. A gate code minted in one tool verifies in every other — it's a content hash, not a model judgement.

Ready Check needs nothing installed. scripts/ready-check.mjs is a single file with zero dependencies — Node 18+ and that one file is the whole PM-side gate. (Only the contract/repo tooling — validate.mjs, build-code-context.mjs — needs js-yaml: cd scripts && npm install.)


The one rule

Never hand-write a Ready Check hand-off, scorecard, or gate code. Always run the CLI and use its output verbatim. A hand-written block looks official and proves nothing — --verify reports UNVERIFIABLE because the • [id] … item list it hashes isn't there. Same for the score: run --scorecard, don't estimate it.


Ready Check — the PM gate (before dev grooming)

Score a PRD against the Definition of Ready, then mint a tamper-evident hand-off.

node scripts/ready-check.mjs --scorecard answers.json     # panel-like status
node scripts/ready-check.mjs --check     answers.json     # verdict JSON (exit 1 if not ready)
node scripts/ready-check.mjs --handoff   answers.json freeze.json   # hand-off + freeze stamp

answers.json:

{ "title": "<feature>",
  "items": {
    "goal":   { "detail": "..." },
    "design": { "na": true, "reason": "why it genuinely doesn't apply" },
    "metric": { "waived": true, "reason": "why it can't be answered yet" }
  } }

Workflow: read the PRD (fetch the link if you can) → map it to the items below → run --scorecard → show it → ask only for the gaps → fold the replies in → re-run until it clears → then --handoff.

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.
