## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 13 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:** 0.27.15
- **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-time configuration writes are first-party OpenCode command and skill setup consistent with the package's plugin role. Inspected executable excerpts establish no concrete malicious behavior, credential exposure, or attack surface.

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 confirmed attack was identified. The postinstall hook places package-owned commands and a skill in OpenCode configuration, while the server supports plugin actions.

- **Trigger:** Package installation runs postinstall; runtime behavior starts when the OpenCode plugin invokes an action.

- **Impact:** This adds first-party OpenCode commands and skill files and enables plan review; inspected excerpts establish no concrete attack effect.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-08T00:30:25.531Z

### AI review details

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

- **Mechanism:** The hook copies bundled command and skill files into OpenCode directories. Server actions load the embedded module, run the configured CLI, and save review edits for the host.

- **Rationale:** The install-time configuration writes are first-party OpenCode command and skill setup consistent with the package's plugin role. Inspected executable excerpts establish no concrete malicious behavior, credential exposure, or attack surface.

- **Files touched:** package.json, dist/server.js

### Review decision

- **Verdict:** Clean

- **Confidence:** 88.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall hook copies package command and skill files into OpenCode's user configuration directories., The server loads its bundled embedded module and launches the configured Plannotator CLI for plugin actions., Plan edits are saved to a backing file and passed to the host review function.

- **Evidence against:** The lifecycle hook installs first-party OpenCode commands and a Plannotator skill; inspected source shows no credential collection or transmission., The inspected server excerpts support the package's plan review and annotation purpose; they show no malicious payload execution.
