debate

debate is a skill for Claude Code, Codex from Magnus-Gille/claude-skills. It costs 0 tokens per session (7,098 once invoked), scanned A, original, MIT.

A structured challenge session in which another AI model reviews a draft, plan, research claim, or design choice.

In plain words
What is it for?
Use it to stress-test proposals and record the review, response, conclusions, and critique history.
Why use it?
It exposes weak assumptions and possible problems before you commit to a decision or publish the work.

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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

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 12d 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 — 436 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Adversarial Debate (cross-model)

Run a structured adversarial review using an external reviewer model. This skill handles the full debate lifecycle: drafting, invoking the reviewer, responding, and recording outcomes. The reviewer is a different model from Claude — the cross-model gap is where the value comes from.

Two reviewer backends are supported, selected per invocation (see Reviewer Selection below):

  • codex — OpenAI Codex CLI. Model-pinnable, stable, and the existing corpus of critique logs was built with it.
  • agy — Google Antigravity CLI (Gemini). The forward path as Codex's free tier winds down.

The entire debate protocol — draft, self-review, response cycle, critique log, summary, index — is identical regardless of backend. Only the Reviewer CLI Invocation section branches by model. Throughout this skill, <reviewer> is a placeholder for the chosen backend (codex or agy); it appears in filenames and in the critique log's source field so cross-model results stay comparable.

Reviewer Selection

Pick the backend at invocation time:

  • Explicit flag: /debate --model agy <topic> or /debate --model codex <topic>.
  • If the user names a model in prose ("debate this with agy"), honor it.
  • Default when unspecified: codex. It is the proven-reliable backend, supports inline model pinning, and keeps the critique-log corpus consistent with prior debates (catch-rate trends stay comparable). Switch the default to agy once its reviewer model is reliably pinned to a Pro tier and its auth is stable in this environment.

Record the chosen backend in the draft header and carry it through every file name and log entry for the debate.

Git Handling

Debate files split into two tiers: searchable artifacts worth tracking, and raw process logs that aren't. Drafts, self-reviews, critiques, responses, and rebuttals are scratch paper — they are load-bearing during the debate and noise afterward. Summaries, critique logs, and the index are the searchable residue that has cross-debate reuse value (decision history, catch-rate tracking, "have I debated this before?" queries).

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.

debate is a skill published in the GitHub repository Magnus-Gille/claude-skills (5 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 7,098 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
