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 reviewed lifecycle code only copies the package’s command and skill assets, and the flagged token-bearing requests target a loopback Inbox service. The download-and-run string is an installation suggestion shown when the CLI is missing, not an automatically executed command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-30T16:57:54.108Z - **Finished:** 2026-10-30T16:58:27.726Z - **Download time:** 775 ms - **Static scan time:** 4335 ms - **AI review time:** 28507 ms - **Total time:** 33618 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 package provides OpenCode plan review and Inbox integration. - **Trigger:** OpenCode loads the plugin; the postinstall hook runs when an installer permits lifecycle scripts. - **Impact:** The observed behavior supports the package’s stated integration; no automatic transmission to an external collector was found. - **Review source:** ai\_review - **Reviewed:** 2026-10-30T16:58:27.726Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies package command stubs and a skill into OpenCode’s config directory. Runtime Inbox requests use a token from a local registry and target 127.0.0.1. - **Rationale:** The reviewed lifecycle code only copies the package’s command and skill assets, and the flagged token-bearing requests target a loopback Inbox service. The download-and-run string is an installation suggestion shown when the CLI is missing, not an automatically executed command. - **Files touched:** ${XDG\_CONFIG\_HOME:-~/.config}/opencode/commands/\*.md, ${XDG\_CONFIG\_HOME:-~/.config}/opencode/skills/plannotator/SKILL.md - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exposes OpenCode plugin entry points for its two supported host versions., The postinstall hook copies the package’s command stubs and skill into OpenCode’s config directory., The flagged credential-bearing request sends to a loopback address and uses a token read from the local Inbox registry., Plugin setup registers OpenCode commands and optional Inbox tools; no external credential receiver was identified. - **Evidence against:** The package runs a postinstall hook that writes files outside the package directory when installed under node\_modules., The plugin uses local filesystem and process environment data to configure its OpenCode and Inbox integrations. ## Affected versions and remediation This report applies to @plannotator/opencode@0.28.39. - Review the evidence and your use of @plannotator/opencode@0.28.39 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.
