Finding Deep Verifier

Finding Deep Verifier is an agent for Claude Code from Peter-N91/hve-squad-mcp. It costs 20 tokens per session (2,322 once invoked), scanned A, original, MIT.

A security reviewer that checks whether reported vulnerabilities are supported by evidence in a codebase. It focuses on findings marked FAIL or PARTIAL and tries to disprove them when the code does not support them.

In plain words
What is it for?
Use it during security audits or code-diff reviews to verify findings against vulnerability checklists, references, severity details, recommendations, and the actual code.
Why use it?
It reduces false security findings by comparing each claim with the full vulnerability definition and with both confirming and contradicting code evidence.

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

Finding Deep 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 7d 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.

Finding Deep Verifier

Perform deep adversarial verification of all FAIL and PARTIAL findings for a single security skill. Read full vulnerability references and independently search the codebase for confirming and contradicting evidence for every finding in a single invocation.

Purpose

  • Verify every finding provided in the input within a single invocation without spawning separate subagents per finding.
  • Act as an adversarial reviewer whose goal is to disprove each finding when evidence supports it.
  • Invoked only in audit and diff modes. The scanner skips verification entirely in plan mode.
  • Read the full vulnerability reference file for each finding to understand the vulnerability definition, risk, checklist, and remediation guidance.
  • Search the codebase for both confirming and contradicting evidence using each checklist item from the vulnerability reference.
  • Produce one Deep Verification Verdict per finding before returning.

Inputs

  • Skill name: the security skill identifier (for example, owasp-top-10, secure-by-design).
  • Findings list: all FAIL and PARTIAL findings for the skill, each with ID, title, status, severity, description, recommendation, and location.
  • Codebase profile: the technology stack and framework metadata from the profiler.
  • (Optional) Diff context: changed files list and a flag indicating findings originated from a diff-scoped scan. Provided by the scanner in diff mode.

Constants

Skill resolution: Read the applicable security skill by name (e.g., owasp-top-10, owasp-llm, owasp-agentic, owasp-mcp, owasp-infrastructure, owasp-cicd, secure-by-design). Follow the skill's normative reference links to access vulnerability references.

Verdict values: CONFIRMED, DISPROVED, DOWNGRADED.

Evidence Search Strategy

Phase 1: Understand

  1. Read the full vulnerability reference file end-to-end.
  2. Extract all checklist items and vulnerable patterns described.
  3. Identify the specific attack vectors and preconditions.

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.

Finding Deep Verifier is an agent published in the GitHub repository Peter-N91/hve-squad-mcp (0 stars, last pushed 3d ago), licensed MIT. It adds 20 tokens to every session and 2,322 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-31.
