When loaded as an OpenCode plugin, it injects workflow instructions and registers package-owned commands and skills. It also provides user-invoked VCS token verification against the configured provider. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 89.0% - **Started:** 2026-08-14T15:50:18.766Z - **Finished:** 2026-08-14T15:51:16.421Z - **Download time:** 505 ms - **Static scan time:** 3610 ms - **AI review time:** 53539 ms - **Total time:** 57655 ms ## Security analysis ### Published attack-surface review - **Summary:** When loaded as an OpenCode plugin, it injects workflow instructions and registers package-owned commands and skills. It also provides user-invoked VCS token verification against the configured provider. - **Trigger:** OpenCode loads the plugin; token verification requires invoking its tool after local configuration. - **Impact:** Can control the host agent's workflow and use a user-configured VCS credential. - **Evidence paths:** package.json, dist/plugin.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T15:51:16.421Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** OpenCode extension configuration and chat-message transformation - **Rationale:** This is a first-party agent extension with meaningful agent-control and credential-use capabilities, warranting a warning under the extension lifecycle policy, but the inspected source does not establish concrete malicious behavior. - **Files touched:** dist/plugin.js, assets/skills, assets/vendor/superpowers/skills - **Network endpoints:** https://gitlab.com/api/v4 ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Runtime plugin injects its workflow bootstrap into chat messages., Plugin mutates OpenCode commands, skill paths, and permissions during configuration., Configured VCS token verification sends a locally supplied token to the configured GitLab API. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., No fixed unofficial credential gateway or package overwrite was found., Token use is inside explicit verification tooling and targets configured/official provider APIs. ## Public findings ### 1.
