## 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:** 0.10.22
- **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 performs automatic, package-aligned pi agent setup by syncing global instructions, initializing a theme, and installing the toolkit's own command. This warrants a warning for agent extension lifecycle risk, but the inspected source does not establish malicious behavior or a publish-blocking attack.

## Latest scan

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 configuration for the pi agent and installs this package's own command and completion file. This is package-aligned agent setup, but it runs automatically during installation.

- **Trigger:** Installing the package with lifecycle scripts enabled.

- **Impact:** The installation changes the user's pi agent configuration and adds the pi-worktree command and shell completion.

- **Evidence paths:** package.json, scripts/install-agents.mjs, packages/worktree/scripts/install.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-12T02:14:36.013Z

### AI review details

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

- **Mechanism:** The hook syncs bundled instructions to the global pi agent directory, fills in a missing theme, and invokes the package's worktree installer.

- **Rationale:** The postinstall hook performs automatic, package-aligned pi agent setup by syncing global instructions, initializing a theme, and installing the toolkit's own command. This warrants a warning for agent extension lifecycle risk, but the inspected source does not establish malicious behavior or a publish-blocking attack.

- **Files touched:** scripts/install-agents.mjs, packages/worktree/scripts/install.mjs, ~/.pi/agent/AGENTS.md, ~/.pi/agent/settings.json, ~/.local/bin/pi-worktree, ~/.local/share/bash-completion/completions/pi-worktree

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The package runs scripts/install-agents.mjs automatically after installation., The hook writes bundled instructions to the global pi agent directory when its existing file differs., The hook initializes the agent theme and installs this package's pi-worktree command., The worktree test uses a temporary repository and removes it on exit., The report generator defines explicit checks, the browser test exercises dashboard interactions, and the browser launcher gates profile copying behind a command-line option., The benchmark utilities validate a supplied source revision and run a caller-provided command; the subagent file defines request interfaces.

- **Evidence against:** The inspected sources show package-aligned pi setup and testing behavior; they do not establish credential collection, exfiltration, or a remote payload chain., The postinstall settings change fills in a missing theme and preserves an existing nonempty theme value.
