Agent skill
vulnerability-validation
Validate security findings for exploitability, reachability, and real-world impact using Bug Hunter-native findings artifacts. Use after security scans, before patch generation, or whenever the user wants confirmation that a suspected vulnerability is actually exploitable.

Vulnerability Validation
This is a bundled local Bug Hunter companion skill. It strengthens the security-specific parts of the Skeptic/Referee process.
Purpose
Take suspected or confirmed security findings and answer:
- Is the vulnerable path reachable?
- Can an attacker control the input?
- Are there existing mitigations?
- How exploitable is it really?
- What is the CVSS / PoC / impact level?
Inputs
Prefer Bug Hunter-native artifacts:
.bug-hunter/findings.json.bug-hunter/threat-model.md.bug-hunter/security-config.json.bug-hunter/dep-findings.jsonwhen dependency issues are involved
Workflow
- Read the findings and isolate the security ones.
- Trace reachability:
- EXTERNAL
- AUTHENTICATED
- INTERNAL
- UNREACHABLE
- Trace exploitability:
- EASY
- MEDIUM
- HARD
- NOT_EXPLOITABLE
- Check for mitigations already present in code, framework behavior, or deployment assumptions.
- For confirmed HIGH/CRITICAL security bugs, generate:
- exploitation path
- benign proof of concept
- CVSS vector + score
- Feed the result back into Bug Hunter-native verdicting.
Outputs
When used as a companion to the main pipeline, keep outputs compatible with:
.bug-hunter/referee.json.bug-hunter/report.md
If a separate validation artifact is helpful for the run, place it under .bug-hunter/validated-findings.json.
Important constraints
- This skill validates findings; it does not replace the normal fix pipeline.
- Keep outputs portable and self-contained under
.bug-hunter/. - Prefer explicit reasoning for false positives so the user can trust dismissals.
Recommended Agent Skills
Expand your agent's capabilities with these related and highly-rated skills.
referee
Final arbiter for Bug Hunter. Receives Hunter findings and Skeptic challenges, independently re-reads code, and delivers authoritative verdicts with CVSS scoring and proof-of-concept generation for security findings.
fixer
Surgical code fixer for Bug Hunter. Implements minimal, precise fixes for verified bugs. Uses doc-lookup (Context Hub + Context7) to verify correct API usage in patches. Respects fix strategy classifications (safe-autofix vs manual-review vs larger-refactor).
hunter
Deep behavioral code analysis agent for Bug Hunter. Performs multi-phase scanning to find logic errors, security vulnerabilities, race conditions, and runtime bugs. Uses doc-lookup (Context Hub + Context7) for framework verification. Reports structured JSON findings.
skeptic
Adversarial code reviewer for Bug Hunter. Rigorously challenges each reported bug to determine if it's real or a false positive. Uses doc-lookup (Context Hub + Context7) to verify framework claims before disproval. The immune system that kills false positives.
commit-security-scan
Scan code changes for security vulnerabilities using Bug Hunter-native artifacts and STRIDE context. Use whenever the user asks for PR security review, commit-diff scanning, staged-change security checks, branch-comparison security review, or pre-merge security analysis of changed code.
security-review
Run a focused STRIDE-based security review using Bug Hunter-native artifacts. Use whenever the user asks for a full security audit, repository security review, weekly security scan, PR security review with deeper validation, or wants dependency CVEs and threat-model context combined into one workflow.
