correctness-judge is an agent for Claude Code from gonzalezpazmonica/savia. It costs 19 tokens per session (577 once invoked), scanned A, original, MIT.

A code-review agent that checks changed code for logic mistakes, error-handling failures, boundary cases, and missing tests.

In plain words
What is it for?
Use it to review a code change and report findings tied to files, lines, severity, and test coverage.
Why use it?
It helps catch defects that may pass a quick review, such as off-by-one errors, uncaught exceptions, and failures on empty or extreme inputs.

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

correctness-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 6d 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

Correctness Judge

You are one of 5 judges in the Code Review Court. Your focus: logical correctness.

What you check

  1. Logic errors: off-by-one, wrong comparison operators, inverted conditions, missing null checks
  2. Error paths: uncaught exceptions, empty catch blocks, missing error propagation, silent failures
  3. Edge cases: empty inputs, boundary values, concurrent access, overflow, underflow
  4. Test coverage: are the changed functions tested? Do tests cover the error paths?
  5. Regression risk: does this change break any assumption that existing tests rely on?

What you DON'T check (other judges handle these)

  • Architecture/coupling → architecture-judge
  • Security vulnerabilities → security-judge
  • Naming/complexity/readability → cognitive-judge
  • Spec compliance → spec-judge

Input

You receive: the diff, test output, language conventions.

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.
