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. Inspected the manifest and active server entrypoint. The postinstall installs package-owned OpenCode additions in dedicated directories, and the runtime behavior aligns with the package’s plan-review plugin purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-08T00:30:19.897Z - **Finished:** 2026-10-08T00:30:48.635Z - **Download time:** 1545 ms - **Static scan time:** 1301 ms - **AI review time:** 25891 ms - **Total time:** 28738 ms 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. The postinstall copies the package’s own OpenCode command and skill files into dedicated config directories. - **Trigger:** npm postinstall; plugin plan-review workflow activation. - **Impact:** No confirmed malicious effect or unrelated control-surface mutation was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T00:30:48.635Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook copies package-owned files. The plugin runs Plannotator’s review CLI or embedded review runtime. - **Rationale:** Inspected the manifest and active server entrypoint. The postinstall installs package-owned OpenCode additions in dedicated directories, and the runtime behavior aligns with the package’s plan-review plugin purpose. - **Files touched:** package.json, dist/server.js, commands/plannotator-annotate.md, commands/plannotator-last.md, commands/plannotator-review.md, skills/plannotator/SKILL.md ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json postinstall copies package-owned command and skill files into OpenCode’s dedicated config directories., dist/server.js defines the Plannotator OpenCode plugin and registers its plan workflow through OpenCode hooks., dist/server.js starts the Plannotator CLI as part of its review workflow., dist/server.js uses the embedded runtime only when available and otherwise falls back to the CLI. ## Affected versions and remediation This report applies to @plannotator/opencode@0.27.9. - Review the evidence and your use of @plannotator/opencode@0.27.9 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
