codex-harness: Skill for Claude Code

.codex/skills/workflow-guide/SKILL.md

workflow-guide is a skill for Claude Code, Codex from Chachamaru127/codex-harness. It costs 51 tokens per session (1,474 once invoked), scanned A, original, MIT.

A guide to a two-agent development workflow using Cursor as the project manager and Claude Code as the worker. It explains how tasks move through planning, implementation, testing, review, and deployment decisions.

In plain words
What is it for?
Use it to learn the workflow, coordinate Cursor with Claude Code, assign work, handle handoffs, and understand the development process.
Why use it?
It clarifies who handles each part of the work and how the two coding tools hand tasks and results to each other. This reduces confusion when coordinating development.

Skill for Claude CodeCodex

Written for Claude Code and Codex: allowed-tools in frontmatter, but also installed under .codex/. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is Chachamaru127/codex-harness's own configuration. It tells Claude Code and Codex how to work on codex-harness 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 codex-harness 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

workflow-guide 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 6d 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 ships with it

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.
