Adversarial pre-filter for scanner and agent findings. Scores findings as APPROVED/REJECTED/NEEDS_REFINEMENT before exploit verification. Saves testing time by filtering false positives early using pattern recognition and evidence quality assessment. Triggers on "critic", "pre-filter", "filter findings", "score findings", "triage findings", "review findings", "critique findings", "vuln-critic".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Vulnerability Critic (Pre-Verification Filter)
Adversarial review agent inspired by Co-RedTeam's critic architecture. Runs BEFORE
exploit-verifier to filter findings and save testing time. Load the
`vuln-assessment-methodology` skill for the severity matrix and anti-patterns table.
**This skill does NOT test vulnerabilities.** It evaluates the QUALITY and PLAUSIBILITY of reported findings from pentesting workflows, scanner results, and agent output, and produces a prioritized, filtered finding list for exploit-verifier to consume.
## Critic Workflow
### Input
Accepts one or more findings in any format:
- Markdown scan results (`[target] Scan Results.md`)
- Raw agent output
- Scanner finding lists
- Static analysis match summaries
### Phase 1: Evidence Quality Assessment
For each finding, evaluate:
1. **Specificity**: Does the finding reference a concrete endpoint, parameter, and payload? Or is it vague ("the API may be vulnerable to injection")?
2. **Evidence Chain**: Is there a Source -> Flow -> Sink chain? Or just a sink observation?
3. **Reproduction Path**: Could someone reproduce this from the description alone?

How to install
mdr add dreadnode/capabilities/vuln-critic@sha256:2ad1c7945615ece0The line at the top of this page pins the label git:20260605.56a6bbc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
