Codex-Workflows: Instructions file for Codex

AGENTS.md

Codex-Workflows AGENTS.md is an instructions file for Codex, OpenCode from robzilla1738/Codex-Workflows. It costs 524 tokens per session, scanned A, original, MIT.

Instructions for a Codex plugin whose source packages and workflow templates are built into an installable plugin bundle. They cover project layout, validation commands, smoke tests, and distribution rules.

In plain words
What is it for?
Use them to add or update workflows, validate the plugin, run simulated workflow checks, test its MCP server, and prepare releases.
Why use it?
They help developers change the source instead of generated output and verify that workflows and plugin metadata still work.

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

Codex-Workflows 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.

Agent instructions

This repo builds a Codex plugin, not a one-off demo. Treat generated artifacts, plugin metadata, and install docs as part of the product.

Project shape

  • Source packages live under packages/.
  • Built-in workflow templates live under workflows/.
  • The installed plugin bundle is generated under plugins/codex-workflows/.
  • Codex skill instructions live under skills/codex-workflows/SKILL.md.
  • The repo marketplace is .agents/plugins/marketplace.json.

Do not edit plugins/codex-workflows/dist/* directly. Change source files, then run pnpm validate:plugin.

Commands

Use these before handing work back:

pnpm typecheck
pnpm test
pnpm validate:plugin

For a fast workflow smoke:

node plugins/codex-workflows/dist/cli.js validate workflows/bug-sweep.workflow.js --cwd /tmp
node plugins/codex-workflows/dist/cli.js run workflows/bug-sweep.workflow.js --cwd /tmp --adapter simulate --no-watch

For MCP smoke testing, start the generated server from plugins/codex-workflows and call workflow_validate.

Distribution rules

  • Keep install docs pointed at robzilla1738/Codex-Workflows.
  • Keep plugin names stable: marketplace codex-workflows, plugin codex-workflows.
  • Keep the plugin bundle self-contained. Users should not need to run pnpm after installing from GitHub.
  • Do not leave /Users/... paths, local cache paths, or machine-specific binaries in the plugin bundle.
  • If package versions change, regenerate the plugin and commit the generated bundle.

Runtime rules

  • Workflow scripts are declarative. They define phases and worker prompts.
  • Workflow scripts must not get direct filesystem, shell, network, process, or Node built-in access.
  • Bug-finding workflows should default to read-only workers.
  • Model overrides from the caller beat workflow defaults.
  • Default durable run state belongs under Codex home so read-only runs do not dirty target repos. Project-local .codex-workflows/runs/<run-id>/ is opt-in and legacy-readable.

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.
