## 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:** 0.3.79
- **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.

No concrete malicious chain, covert exfiltration, or broad AI-agent control-surface takeover was found. The install-time third-party agent dependency patch remains a real lifecycle risk and merits a warning.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 86.0%
- **Started:** 2026-07-27T12:43:55.648Z

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:** Installation mutates one exact file in the pi-coding-agent dependency. Runtime commands can bootstrap a marketplace and expose a local agent-control web bridge only when the CLI is invoked.

- **Trigger:** npm postinstall; later explicit crtr CLI commands

- **Impact:** Dependency behavior changes at install; user-invoked runtime may create local agent state and fetch configured marketplace content.

- **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli.js, dist/core/bootstrap.js, dist/core/auto-update.js, dist/clients/web/server.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-27T12:45:11.692Z

### AI review details

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

- **Mechanism:** dependency patch plus agent runtime/bootstrap

- **Rationale:** No concrete malicious chain, covert exfiltration, or broad AI-agent control-surface takeover was found. The install-time third-party agent dependency patch remains a real lifecycle risk and merits a warning.

- **Files touched:** scripts/postinstall.mjs, node\_modules/@earendil-works/pi-coding-agent/dist/modes/interactive/components/tree-selector.js, .crouter/, ~/.crouter/marketplaces/crouter-official-marketplace

- **Network endpoints:** https://github.com/crouton-labs/crouter-official-marketplace.git, fcm.googleapis.com, updates.push.services.mozilla.com, web.push.apple.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** postinstall rewrites a version-pinned pi-coding-agent file, CLI bootstrap clones an official marketplace on ordinary commands, CLI can run configured agent/plugin setup commands

- **Evidence against:** postinstall change is a narrow, documented tree-order UI patch, no install-time credential harvesting or exfiltration found, web command is user-invoked, loopback by default, and requires a token off-loopback, push outbound endpoints are restricted to vendor push-service hosts
