## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.11.19
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The postinstall hook automatically changes global agent instructions, so this package has a concrete agent setup capability with user-wide effects. The bundled content is ordinary coding guidance and the inspected source does not establish credential theft or another active attack; classify as warning-level lifecycle risk.

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** The postinstall hook changes global pi agent configuration by syncing this package's bundled instructions. This is automatic setup for the package's agent environment, but it can replace a differing user file.

- **Trigger:** Installing the package through npm, which runs its postinstall hook.

- **Impact:** The global agent instructions change and may affect later pi agent sessions. No credential transfer or other concrete attack behavior was established.

- **Evidence paths:** package.json, scripts/install-agents.mjs, global/AGENTS.md

- **Review source:** ai\_review

- **Reviewed:** 2026-10-14T13:08:37.908Z

### AI review details

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

- **Mechanism:** The hook writes the bundled instructions to ~/.pi/agent/AGENTS.md when the existing file is absent or differs.

- **Rationale:** The postinstall hook automatically changes global agent instructions, so this package has a concrete agent setup capability with user-wide effects. The bundled content is ordinary coding guidance and the inspected source does not establish credential theft or another active attack; classify as warning-level lifecycle risk.

- **Files touched:** ~/.pi/agent/AGENTS.md

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The install hook targets the user's global pi agent directory and its AGENTS.md file., package.json runs scripts/install-agents.mjs during postinstall., The hook replaces that AGENTS.md when it is missing or differs from the bundled file., The bundled file contains general coding guidance for LLMs, with project-specific instructions taking precedence., The same hook sets a missing default theme and installs the pi-worktree command in the user's home directory.
