/security plugin-audit [path|url]

Audit a Claude Code plugin for security before installation. Accepts local paths or GitHub URLs.

Step 1: Resolve Target

• If $ARGUMENTS contains --branch <name> → strip it, set branch = <name>
• If $ARGUMENTS starts with https://github.com/ or git@github.com: → Run: node <plugin-root>/scanners/lib/git-clone.mjs clone "<url>" [--branch <branch>] If exit code != 0 → show error to user and STOP Set clone_path = stdout (trimmed), target = clone_path Set remote_url = <url> for display
• Else if $ARGUMENTS is non-empty → target = $ARGUMENTS, clone_path = null
• Else → target = ".", clone_path = null
• Verify .claude-plugin/plugin.json exists at <target>. If not and clone_path != null → cleanup clone_path first, then tell user this is not a plugin directory and STOP. If not and local → tell user and STOP.

Step 1.5: Pre-extraction (remote audits only)

If clone_path != null: Get temp path: node <plugin-root>/scanners/lib/fs-utils.mjs tmppath "plugin-extract.json" Run: node <plugin-root>/scanners/content-extractor.mjs "<target>" --output-file "<evidence_file>" If exit code != 0 → set evidence_file = null (fall back to direct scan)

Step 2: Inventory

Read plugin.json (name, version, auto_discover). Glob for commands, agents, hooks, skills, knowledge. Build permission matrix from all allowed-tools and tools declarations. Flag: Bash access, Bash+Write combo, Task (sub-agent spawning), opus for trivial tasks.

Step 3: Analyze Hooks

If hooks/hooks.json exists: parse events, read scripts, classify (block/warn/modify). Flag: state modification, network calls, non-CLAUDE env vars, SessionStart hooks.

Step 4: Scan Content

Spawn subagent_type: "llm-security:skill-scanner-agent", model: "sonnet":

If evidence_file is set:

EVIDENCE-PACKAGE MODE. Read: <evidence_file> Read: <plugin-root>/knowledge/skill-threat-patterns.md Analyze all sections. DO NOT use Read/Glob/Grep on the target directory. Check all 7 threat categories. Return findings: file, severity, OWASP ref.

Otherwise:

Scan plugin at <path>: commands/.md, agents/.md, hooks/scripts/, skills//SKILL.md, knowledge/**/*.md. Read: <plugin-root>/knowledge/skill-threat-patterns.md Check all 7 threat categories. Return findings: file, severity, OWASP ref.

Step 5: Report

Output: Plugin metadata, component inventory, permission matrix, hook analysis, security findings, trust verdict.

Verdict: Install (0 critical/high, transparent hooks) | Review (high findings or unclear permissions) | Do Not Install (critical, exfiltration, persistence, or hidden instructions).

Step 6: Cleanup (only if remote)

If clone_path != null: Run: node <plugin-root>/scanners/lib/git-clone.mjs cleanup "<clone_path>" If cleanup fails → warn: "Could not remove temp dir <clone_path> — remove manually."
