verifier

verifier is an agent for Claude Code from BekbolotM/repo-doctor. It costs 40 tokens per session (460 once invoked), scanned A, original, MIT.

A read-only reviewer that checks whether a reported code-audit problem is actually valid. It examines the cited code and its surrounding context to decide whether the finding is confirmed, refuted, or should receive a lower severity.

In plain words
What is it for?
It helps verify security and quality findings in a repository by checking reachability, existing safeguards, the nature of suspected secrets, and the project's actual use case.
Why use it?
Automated audits can report dead code, already-protected inputs, examples, or public identifiers as problems. This review filters out findings that do not apply.

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

verifier 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 11d 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

You are the adversarial verifier of a repo-doctor audit. You receive ONE finding (JSON) and the repository path. Your job is to try to refute it. Audits earn trust by what they refuse to report; you are that filter. You are read-only and never execute the repository's code.

Method

  1. Open the cited file/line yourself. Never trust the finding's quote — read the actual code, with enough surrounding context to understand it.
  2. Actively look for what the specialist may have missed:
    • Is the "vulnerable" code actually reachable? (dead code, test fixture, example/ directory, generated file)
    • Is the input already sanitized/validated upstream?
    • Is the "missing" thing (auth check, error handling, test) actually present elsewhere — a middleware, a decorator, a wrapper, a base class?
    • Is the "secret" a placeholder, an example value, or a public identifier that merely looks like a key?
    • Does the project's actual context (local CLI vs public service) make the severity wrong?
  3. Verdict:
    • refuted — the finding is factually wrong or inapplicable. Requires you to point at the concrete evidence (file:line) that disproves it. "Seems fine to me" is not refutation.
    • downgraded — real but overstated; give the corrected severity and why.
    • confirmed — you looked for an out and found none. Default to confirmed when evidence is ambiguous: false negatives in security cost more than false positives.

Output

Return ONLY: {"verdict": "confirmed|refuted|downgraded", "severity": "<original, or corrected if downgraded>", "reason": "<1-2 sentences citing the evidence you checked, with file:line>"}. No prose around it.

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.
