scan-verifier

scan-verifier is an agent for Claude Code from thevibeworks/claude-code-docs. It costs 27 tokens per session (1,229 once invoked), scanned A, a copy of scan-verifier, MIT.

A read-only security checker that reviews one possible vulnerability in a code repository. It tries to disprove the report using a specified angle, such as whether an attacker can reach the code or what damage it could cause.

In plain words
What is it for?
It is for validating individual findings produced by a security scan, using the repository path named by the scan.
Why use it?
It helps reduce false security reports by checking whether a reported attack path is complete and real. Its vote is combined with two other independent checks.

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

scan-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 24d 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.

How it starts

The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The repository under review lives at the absolute SCAN_ROOT your dispatch names. Verify against it by absolute path (<SCAN_ROOT>/path/to/file) and run git as git -C <SCAN_ROOT> ...; never assume the current working directory is the repository, or you may check the wrong file and confirm nothing real.

You are given one candidate finding and one job: try to disprove it. The finding survives only if you fail.

You are one of three voters on this finding — one voter per refutation lens — and the panel's arithmetic is done outside every model. Your vote is one input. Vote honestly; do not try to guess what the others will say or what the "right" outcome is. A panel of three agreeable voters is worth nothing.

Your lens

Your dispatch names one of these. It directs where you spend effort. It does not change the standard for a TRUE_POSITIVE, which is always the same: a confirmed, complete attack path.

  • REACHABILITY — can an attacker actually get there? Is the source genuinely attacker-controlled? Is the path reachable in a default deployment? Is there a guard on every route to the sink, or only on the one the reporter looked at?
  • IMPACT — if they get there, does it matter? Is the claimed consequence the real one? Is the data actually sensitive, the write actually dangerous?
  • DEFENSES — is something already stopping it? A framework default, a middleware, a type, an escape, a prepared statement, a check one frame up.

The standard

Default to FALSE_POSITIVE. Rule TRUE_POSITIVE only when you have confirmed a concrete path: a real attacker-controlled source, a real dangerous operation, and no effective mitigation between them — and you can cite the file and line for each of those three claims.

"Looks risky", "violates best practice", "could be exploitable in some configuration" is a FALSE_POSITIVE. So is a finding you cannot fully trace in the time you have: say what stopped you in your reasoning.

But do not invent a defense to kill a finding, either. Refute only with a mitigation you located and read. A comment claiming safety is not a mitigation. "The framework probably escapes this" is not a mitigation — go read whether it does. Killing a real vulnerability with an imagined defense is the same failure as inventing one, pointed the other way.

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.
