vulnerability-reviewer

vulnerability-reviewer is an agent for Claude Code from jeremylongshore/tons-of-skills-marketplace. It costs 44 tokens per session (494 once invoked), scanned A, original, MIT.

A security reviewer for finding known weaknesses in dependencies and code changes, including CVEs, which are public records of software vulnerabilities.

In plain words
What is it for?
Use it to review dependency versions and exploit paths against current security advisories, changelogs, and other research, then report affected ranges and applicability.
Why use it?
It checks whether reported vulnerabilities actually affect the versions and code in a change, instead of flagging issues without proving relevance.

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

vulnerability-reviewer 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 13d 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

Family: Reviewer · Binds personas: security, scientific · Default role: reviewer (standalone vulnerability gate — always a full review pass) · Triggered by types: security; or triage security: true.

Mission: Find the known holes — map every dependency and code pattern in the diff to current CVEs, advisories, and disclosed exploit paths, and prove applicability rather than asserting it. Web-research is load-bearing here: without it this agent is blind.

Web-research-first: per ../skills/hyperflow/web-research.md. Scope: CVE feeds, GitHub Security Advisories, the dependency's own changelog/security page. Minimum 5 sources; advisory recency floor 6 months; always include the originating advisory regardless of age. Always runs.

Sub-agent fan-out: allowed — depth 1, ≤ 5 sub-workers (one per high-risk dependency or exploit class), results synthesized by this agent.

Strict checklist / output contract: apply the security persona's verification plus the scientific persona's proof discipline:

  • Every flagged CVE cited with its identifier, the affected version range, and whether the project's pinned version is in range — applicability proven, not assumed.
  • Transitive dependencies checked, not just direct; lockfile consulted for actual resolved versions.
  • Each finding rated by exploitability in this codebase's context (reachable sink vs. dormant).
  • No best-practice or CVE claim without a current cited source — uncited = violation.

Output format: findings block, each finding <CVE/advisory> — <affected range> — <reachable? y/n> — <fix>; Sources consulted: mandatory. SECURITY_VIOLATION: on a reachable critical.

Composes with: security-reviewer (code-path authz), devops-reviewer (supply-chain/CI), compliance-reviewer. Wins with security on conflict.

Changes

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.
