## 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:** 0.3.83
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM treats this as warn-only first-party agent extension lifecycle risk. Install mutates one dependency UI file; later CLI use can write package-generated command prompts to existing Claude/Pi directories. No credential exfiltration or remote payload execution was confirmed.

## Security analysis

### Published attack-surface review

- **Summary:** Install mutates one dependency UI file; later CLI use can write package-generated command prompts to existing Claude/Pi directories. No credential exfiltration or remote payload execution was confirmed.

- **Trigger:** npm postinstall; subsequently running a non-help crouter CLI command

- **Impact:** Changes dependency behavior and can add or update crouter-owned AI-host command files.

- **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli.js, dist/core/host-exports/export.js, dist/clients/web/server.js, dist/core/view/transport-local.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-27T12:45:18.249Z

### AI review details

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

- **Mechanism:** dependency patch and guarded AI-host prompt provisioning

- **Rationale:** Source inspection found no concrete malicious behavior, but automatic dependency mutation plus CLI-triggered AI-host prompt provisioning warrants a warning under the lifecycle-risk policy.

- **Files touched:** scripts/postinstall.mjs, dist/cli.js, dist/core/host-exports/export.js, dist/core/host-exports/builtins.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** \`postinstall\` patches a file inside \`@earendil-works/pi-coding-agent\`., Every non-help CLI invocation provisions generated prompts into existing \`~/.claude\`/\`~/.pi\` host directories.

- **Evidence against:** Postinstall patch is version-guarded, idempotent, and only changes Pi tree-root ordering., Host exports are marker-guarded and avoid overwriting user-owned files., No install-time network, credential harvesting, or payload download found., Web command surface defaults to loopback; non-loopback binding requires a token.
