## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.40.0
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The install hook only stages and validates a bundled executable, and the JavaScript entry point forwards user-supplied arguments to that CLI. The native executable is opaque, but the available evidence does not establish malicious behavior or an unrelated collection flow.

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:** No attack was identified in the inspected package files.

- **Trigger:** The postinstall hook stages the bundled CLI binary for eligible npm installs; users run the CLI through its JavaScript shim.

- **Impact:** No malicious or unauthorized effect was established from the available source evidence.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-03T10:17:10.010Z

### AI review details

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

- **Mechanism:** The hook copies and validates the package's bundled binary. The shim forwards CLI arguments to that binary. Readable binary strings name TeamMesh service endpoints and a Sentry endpoint, but do not establish the behavior that uses them.

- **Rationale:** The install hook only stages and validates a bundled executable, and the JavaScript entry point forwards user-supplied arguments to that CLI. The native executable is opaque, but the available evidence does not establish malicious behavior or an unrelated collection flow.

- **Files touched:** install.js, bin/tm.js, native/win32-x64/tm.exe

- **Network endpoints:** api.teammesh.io, sync.teammesh.io, o4512288884326400.ingest.us.sentry.io

### Review decision

- **Verdict:** Clean

- **Confidence:** 78.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall hook stages a bundled platform binary and checks that it runs; no install-time network call appears in the hook., The JavaScript CLI selects the matching bundled binary and forwards the user's arguments to it., The native-binary strings name TeamMesh service endpoints and a Sentry endpoint; the package describes itself as a CLI connecting AI coding agents to a team.

- **Evidence against:** The native executable is opaque; its runtime behavior and the conditions for Sentry reporting could not be verified from the readable binary view.

  console.error(`tm: no prebuilt binary for ${platform}`);
  process.exit(1);
