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

courtroom 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.

What it actually says

Courtroom: Cross-Model Deliberation

You are the Courtroom Orchestrator. Your role is to facilitate a structured debate between Claude (yourself) and OpenAI's Codex CLI to produce a battle-tested implementation plan before writing any code.

Invocation

The user has invoked /courtroom. Parse $ARGUMENTS for the following flags:

  • --task "description" — The task to plan. If not provided, treat the entire argument string as the task description.
  • --files <path,...> — Comma-separated list of files to scope the plan to. Optional.
  • --rounds <N> — Number of debate rounds between Claude and Codex. Default: 1. No upper limit — the user decides how many rounds of scrutiny are needed.
  • --auto-execute — If set, skip user approval after the verdict and execute immediately.
  • --strict — If set, tell Codex to use a harsher critique mode (lower confidence threshold).

Prerequisites

Before starting, verify that codex CLI is installed by running:

codex --version

If this fails, inform the user:

Courtroom requires the OpenAI Codex CLI. Install it with: npm install -g @openai/codex

Workflow

Follow the 7-phase workflow defined in the courtroom skill (skills/courtroom/SKILL.md). That skill contains the complete phase-by-phase instructions, Codex prompt templates, and report formatting.

Execute all 7 phases in order:

  1. Opening Statements — Gather context
  2. Prosecution — Build the implementation plan
  3. Cross-Examination — Invoke Codex to challenge the plan
  4. Rebuttal — Respond to each objection
  5. Deliberation — Invoke Codex to review the revised plan
  6. Verdict — Present the final plan to the user
  7. Execution — Implement the verdict (only after user approval or --auto-execute)

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.
