mindroom: Skill for Claude Code

.claude/skills/code-debate/SKILL.md

code-debate is a skill for Claude Code from mindroom-ai/mindroom. It costs 35 tokens per session (3,889 once invoked), scanned A, original, Apache-2.0.

A protocol for two coding agents to review a code change from opposing positions through a shared DEBATE.md file.

In plain words
What is it for?
Use it for adversarial review of a commit, code diff, or pull request by starting one agent as A and another as B.
Why use it?
It gives the agents a common place to record an opening analysis and response, making disagreements and risks easier to inspect.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: positional $N argument; mentions Claude Code; mentions Codex.

This is mindroom-ai/mindroom's own configuration. It tells Claude Code how to work on mindroom 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 mindroom 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

code-debate 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.

How it starts

The opening of the file, as written. The whole thing — 325 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Debate Protocol

A protocol for two coding agents (Claude Code, Gemini CLI, Codex, or any other) to debate code changes through a shared file (DEBATE.md). Both agents receive this same prompt. Role is determined by the first argument.

This skill assumes the two debate participants are started externally by a human in separate sessions. It is not a peer-orchestration skill.

How to use

Open two terminal tabs with coding agents (same or different). Invoke this skill in each, specifying role and subject:

  • /code-debate A <subject> — opener, creates DEBATE.md with the first analysis
  • /code-debate B <subject> — responder, waits for DEBATE.md then replies

Role detection

Your role is determined by the first argument ($0):

  • A → you are Agent A (opener). Create DEBATE.md and write the opening position.
  • B → you are Agent B (responder). Poll and wait for DEBATE.md to exist, then read it and respond.

If no role argument is provided, fall back to file existence:

  • If DEBATE.md does not exist → you are Agent A (opener).
  • If DEBATE.md already exists → you are Agent B (responder).

Do not ask the user which role to play.

Non-simulation guardrails (MUST)

  • Never write content for the opposite role.
  • Never simulate, fabricate, or placeholder the other agent's response.
  • Never append both sides of a debate from one process.
  • Never create, spawn, launch, delegate to, summon, or recruit the opposite debate role.
  • Never use spawn_agent, send_input, tmux supervision, background shell automation, or any other tool to manufacture the missing peer.
  • Role is immutable for the run: once detected as Agent A or Agent B, keep that role until ## CONSENSUS.
  • If you are about to write the opposite role, stop and report protocol violation instead of writing.
  • After appending your section, only poll.
  • Append another turn only after consuming the expected signed peer turn, even if it arrived before polling started.
  • Without an unconsumed peer turn, keep polling until timeout or ## CONSENSUS.
  • On timeout, use APPEND_TIMEOUT to close any unfinished fence and publish only a timeout ## CONSENSUS from your own role.

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.
