When loaded as an OpenCode plugin, it injects bundled commands, skill paths, permission rules, and workflow text into host sessions. This is a package-owned agent-extension control surface, not install-time persistence. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-15T17:44:39.983Z - **Finished:** 2026-08-15T17:45:44.047Z - **Download time:** 517 ms - **Static scan time:** 2647 ms - **AI review time:** 60900 ms - **Total time:** 64064 ms ## Security analysis ### Published attack-surface review - **Summary:** When loaded as an OpenCode plugin, it injects bundled commands, skill paths, permission rules, and workflow text into host sessions. This is a package-owned agent-extension control surface, not install-time persistence. - **Trigger:** OpenCode loads the installed plugin and processes a session. - **Impact:** Can steer agent workflow and modify in-memory host plugin configuration; configured API tools can use user-provided service tokens. - **Evidence paths:** package.json, dist/plugin.js - **Review source:** ai\_review - **Reviewed:** 2026-08-15T17:45:44.047Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** OpenCode configuration and chat-message hook mutation - **Rationale:** No concrete malicious chain was found, but runtime mutation of host agent configuration and user messages warrants a warning under the extension-lifecycle policy. - **Files touched:** dist/plugin.js, assets/commands/, assets/skills/, assets/vendor/superpowers/skills/ - **Network endpoints:** https://gitlab.com/api/v4, https://enghouseamg.youtrack.cloud ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Runtime plugin mutates OpenCode command, skill-path, and permission configuration., Chat hook prepends a bundled workflow bootstrap to user messages., Configured service tokens are sent only to configured GitLab/YouTrack API requests. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., No fixed unofficial credential gateway or foreign package overwrite was found., Network requests use configured service URLs rather than a package-controlled endpoint. ## Public findings ### 1.
