Those plugins subsequently alter project agent configuration and can automatically install external skills. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-07-23T12:11:39.881Z - **Finished:** 2026-07-23T12:12:17.824Z - **Download time:** 520 ms - **Static scan time:** 87 ms - **AI review time:** 37335 ms - **Total time:** 37943 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall mutates the user's OpenCode configuration and installs package-controlled plugins and agents. Those plugins subsequently alter project agent configuration and can automatically install external skills. - **Trigger:** npm postinstall; then OpenCode session creation/first chat message - **Impact:** Changes the default agent, broadens agent directory permission, loads package code, and enables later external npx execution. - **Evidence paths:** package.json, install.js, plugins/AutoDiscoveryPlugin.ts - **Review source:** ai\_review - **Reviewed:** 2026-07-23T12:12:17.824Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented global AI-agent configuration mutation and automatic extension installation - **Attack narrative:** Installing the package automatically executes install.js, which writes into the user's OpenCode control surface, registers its plugins, changes the default agent, and grants wildcard external-directory access. Once loaded by OpenCode, AutoDiscoveryPlugin inspects project manifests, automatically invokes npx to globally install skills, writes enabled MCP server commands into project configuration, and injects content into the agent system prompt. - **Rationale:** This is a concrete unconsented postinstall mutation of a broad foreign AI-agent control surface, meeting the blocking policy. The subsequent plugin behavior compounds the risk through automatic extension installation and agent-control changes. - **Files touched:** ~/.config/opencode/plugins/, ~/.config/opencode/agents/, ~/.config/opencode/opencode.jsonc, ~/.config/opencode/opencode.json, ~/.agents/skills/, \/.opencode/opencode.jsonc, \/.agents/auto-discovery.json ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs install.js via postinstall., install.js copies bundled plugins/agents into ~/.config/opencode., install.js rewrites opencode config, sets default\_agent, and grants external\_directory '\*' allow., AutoDiscoveryPlugin runs npx skills add -g automatically from session activity., AutoDiscoveryPlugin adds enabled local MCP commands and injects system-prompt content. - **Evidence against:** No direct credential harvesting or package-owned exfiltration endpoint found., No obfuscated payload, eval, or remote code download in the lifecycle script. ## Public findings ### 1.
