## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 34 low-signal pattern(s) reviewed.

- **Verdict:** Manual Review
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Under Review
- **Threat category:** Unknown
- **Selected version:** 0.3.328
- **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy.

No confirmed attack surface was established. Postinstall installs this package's runtime under its own home and the pi extension rewrites prompt shims only after explicit setup. A clean verdict cannot be finalized because the required citation list exceeds the citation cap.

## Security analysis

### Published attack-surface review

- **Summary:** No confirmed attack surface was established. Postinstall installs this package's runtime under its own home and the pi extension rewrites prompt shims only after explicit setup. A clean verdict cannot be finalized because the required citation list exceeds the citation cap.

- **Trigger:** npm postinstall, or a later user command that loads the pi extension.

- **Impact:** No unconsented foreign agent-control write, credential export, or remote payload execution was confirmed. The review stays unresolved only because clean citation coverage cannot be completed.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-26T16:37:41.135Z

### AI review details

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

- **Mechanism:** The install hook copies a sealed runtime generation locally with npm ci --ignore-scripts. Agent shim writes occur only when the extension's resources\_discover hook runs.

- **Rationale:** The install hook and the Claude/pi extension match a local agent runtime and an explicit setup command, without a concrete malicious chain. Clean cannot be returned because sixteen required citations exceed the eight-citation limit, so the result is manual review.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 62.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** High

- **AI review observations:** npm postinstall runs scripts/postinstall.mjs, which stages a local runtime and does not write ~/.claude or ~/.pi., The runtime home is ~/.crouter/runtime (or CRTR\_RUNTIME\_HOME), and the nested npm ci uses --ignore-scripts so the lifecycle hook does not re-enter., Claude command shims are rebuilt only inside a pi extension on resources\_discover, after the user runs crtr sys setup., A clean decision would need sixteen distinct citations, but the schema allows eight, and no separate concrete attack was established.

- **Evidence against:** Postinstall spawns the local runtime installer and patches @earendil-works/pi-coding-agent inside node\_modules., When a user invokes a surfaced slash command, the extension can run shell blocks from that user's own Claude command or skill file.
