## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Unconsented persistent modification of foreign AI-agent control surfaces.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.12.0
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. Installation mutates global Claude and shared .agents skill directories when they already exist. The dropped skill directs agent behavior broadly and grants shell access to rig and tapd commands.

## Security analysis

### Published attack-surface review

- **Summary:** Installation mutates global Claude and shared .agents skill directories when they already exist. The dropped skill directs agent behavior broadly and grants shell access to rig and tapd commands.

- **Trigger:** npm install executes postinstall.

- **Impact:** Unconsented persistent modification of foreign AI-agent control surfaces.

- **Evidence paths:** package.json, bin/postinstall.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-17T17:33:53.542Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Install-time global AI-agent skill deployment.

- **Attack narrative:** Installing the package runs bin/postinstall.mjs. When ~/.claude or ~/.agents exists, it creates skills/rig/SKILL.md and writes a behavior-bearing agent skill. This occurs without an explicit rig command and affects global agent behavior outside a project workspace; the skill includes broad trigger instructions and permits shell commands.

- **Rationale:** Direct source inspection confirms an unconsented postinstall write to global AI-agent skill locations. Collision checks reduce overwrite risk but do not remove the foreign control-surface mutation.

- **Files touched:** bin/postinstall.mjs, ~/.claude/skills/rig/SKILL.md, ~/.agents/skills/rig/SKILL.md

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** npm postinstall executes bin/postinstall.mjs., Postinstall writes a generated SKILL.md into existing ~/.claude and ~/.agents agent-control directories., Installed skill has broad automatic trigger guidance and Bash access to rig/tapd commands.

- **Evidence against:** Hook does not create absent harness home directories., It avoids overwriting an unrelated existing rig skill.
