workfile: Instructions file for Codex

AGENTS.md

workfile AGENTS.md is an instructions file for Codex, OpenCode from illodev/workfile. It costs 273 tokens per session, scanned A, original, MIT.

Project instructions for Workfile, a tool that stores searchable project context and tracks work items. They define required preparation, change tracking, review states, and verification steps.

In plain words
What is it for?
Use them when changing an illodev/workfile project: read the required protocol and workflow, search existing context, claim work cards, record discoveries, and run the project health check before finishing.
Why use it?
They give contributors a shared process for making changes and recording what remains to be done. This helps prevent undocumented work and treats completion as something that needs runtime evidence.

Instructions file for CodexOpenCode

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

This is illodev/workfile's own configuration. It tells Codex and OpenCode how to work on workfile 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 workfile 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

workfile 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.

What it actually says

Workfile for AGENTS.md

Before substantial changes, read .project/agents/protocol.md and the relevant workflow under .project/agents/workflows.

Critical rules:

  • Search context with pnpm workfile search or pnpm workfile agents context.
  • Claim cards before modifying their scope.
  • Use CLI/MCP for protocol mutations.
  • Two exits, and say which: review only when every criterion is met and just runtime evidence is missing; otherwise next/blocked with the reason in a note. review is not "my turn ended".
  • done requires evidence from where the change actually runs.
  • Acceptance criteria live under ## Acceptance criteria; checkboxes are only for criteria; a criterion with a false premise is rewritten with the measurement, not left unmarked.
  • Finish discovered work rather than carding it when it is the same file and the same run; card what you cannot do, and record durable knowledge.
  • Run pnpm workfile doctor before finishing.
Changes

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.
