vet-repo
This skill scans repository agent configuration files (.claude/, .mcp.json, CLAUDE.md) for malicious patterns and emits a structured report. It instructs running python3 "$SKILL_DIR/scripts/vet_repo.py" "$PROJECT_ROOT" (local shell execution); no external network calls or secret exfiltration are instructed.
vet-repo -- Repository Agent Config Scanner
Scan all agent configuration files in a repository for known malicious patterns. Use this when entering an unfamiliar codebase to assess agent-level security risks before trusting the repo's configurations.
What to do
Run the scanner script against the current project root:
python3 "$SKILL_DIR/scripts/vet_repo.py" "$PROJECT_ROOT"
Where $SKILL_DIR is the directory containing this SKILL.md, and $PROJECT_ROOT is the root of the repository being scanned.
What it scans
.claude/settings.json-- hook configs (auto-approve, stop loops, env persistence).claude/skills/-- all SKILL.md files (hidden comments, curl|bash, persistence triggers).mcp.json-- MCP server configs (unknown URLs, env var expansion, broad tools)CLAUDE.md/.claude/CLAUDE.md-- instruction injection in project config
Output
Structured report with findings grouped by severity (CRITICAL, HIGH, MEDIUM, LOW, INFO) and actionable recommendations for each finding.
When to use
- Before trusting a cloned repository's agent configurations
- After pulling changes that modify
.claude/or.mcp.json - As part of a security review of any codebase with agent integration
