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

fight 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 8d 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.

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/fight

Run every fight-club reviewer against the target and produce a combined report.

The user invoked this command with: $ARGUMENTS

Step 1: Get the code

Parse $ARGUMENTS to determine the target:

  • File path → read the file
  • Number → gh pr diff <number> to get the PR diff
  • "diff" or empty → git diff HEAD

Step 2: Run all reviewers

Apply each of these lenses to the code. For each, produce findings using that skill's output format:

  1. Adversarial Architect — design, factoring, coupling, abstraction
  2. Adversarial Auditor — vulnerabilities, trust boundaries, data exposure
  3. Adversarial Optimizer — scaling assumptions, inefficiencies, hot paths
  4. Adversarial QA — coverage gaps, weak assertions, missing failure modes
  5. Adversarial SRE — production failure scenarios, silent failures, recovery risk

Step 3: Aggregate

After all reviewers, produce a summary:

## Fight Club Report

### Adversarial Architect
[findings or "No issues found"]
Verdict: Composable | Acceptable | Poor | Broken

### Adversarial Auditor
[findings or "No issues found"]
Verdict: Secure | Hardening Needed | Vulnerable | Critical

### Adversarial Optimizer
[findings or "No issues found"]
Verdict: Efficient | Optimization Needed | Will Not Scale | Blocking Issue

### Adversarial QA
[findings or "No issues found"]
Verdict: Solid | Needs Work | Insufficient | No Confidence

### Adversarial SRE
[findings or "No issues found"]
Verdict: Ready to Ship | Needs Hardening | High Risk | Do Not Ship

## Blocking (must fix before merge)
[Cross-lens list of every finding with Blocking: Yes. Empty section if none.]

## Follow-up (track as issues, do not block merge)
[Cross-lens list of every finding with Blocking: No. Group by lens.]

## Overall Verdict
[APPROVED / APPROVED (with follow-ups) / NEEDS WORK / REJECT]
[2-3 sentences: biggest risks, blockers, recommended next action]

Verdict rules

The overall verdict is determined by Blocking findings, not by severity alone:

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.
