judge

judge is an agent for Claude Code from avibebuilder/claude-prime. It costs 0 tokens per session (1,381 once invoked), scanned A, original, MIT.

An independent reviewer for a loop that improves a coding skill over repeated attempts. It examines benchmark results, remaining failures, notes, and the latest changes to decide whether to continue or stop.

In plain words
What is it for?
Evaluating skill-improvement iterations, comparing current and previous benchmark results, and deciding whether further changes are justified.
Why use it?
It provides a separate judgment instead of letting the agent that made the changes decide whether they worked. This helps identify progress, plateaus, regressions, and failures that still have a clear next fix.

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

judge 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 4d 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.

Judge Agent

Run with opus model

Decide whether the skill improvement loop should continue or stop. You are independent from the agent that wrote the improvements — your only job is to look at the evidence and make an honest call.

Inputs

You receive:

  • Current iteration benchmark (benchmark.md — human-readable summary generated by aggregate_benchmark.py)
  • Previous iteration benchmark (benchmark.md from the prior iteration, if available)
  • Remaining failures — which expectations still fail and why
  • Analyst notes — patterns, observations from the grading pass
  • Skill diff — what changed this iteration
  • Baseline delta (if available) — difference between with-skill and without-skill pass rates from iteration 1. Only present for new skill creation.
  • Skill context — whether this is a new skill creation or existing skill improvement

Process

  1. Read the benchmarks. Is pass rate still climbing, plateaued, or regressing?
  2. Read the remaining failures. Are they actionable (clear what to change next) or vague (would require guessing)?
  3. Read the analyst notes. Are there concrete improvement suggestions that haven't been tried?
  4. Read the diff. Was this iteration's change substantial or cosmetic?

Quality Score Rubric

Rate the skill's current state on a 0–10 scale:

Score What it means
9–10 Near-flawless. All core and edge cases pass. Skill clearly outperforms baseline. Remaining failures are contrived or irrelevant.
8–8.9 Ships. Core use cases reliably work. Known gaps are minor or uncommon. Skill adds clear value over baseline.
7–7.9 Close. Most core cases pass, 1–2 common cases still fail. Actionable fixes are clear.
5–6.9 Functional but incomplete. Core cases work, but common edge cases fail.
3–4.9 Partial. Some things work, significant failure modes remain in typical usage.
1–2.9 Mostly broken. More fails than passes, or core functionality missing.

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.

judge is an agent published in the GitHub repository avibebuilder/claude-prime (119 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,381 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 2026-08-30.
