Future OpenCode sessions load package-authored directives without an explicit setup command. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.39.6 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically changes the user's OpenCode instruction configuration. The added file tells agents that package directives are binding. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-31T20:45:21.516Z - **Finished:** 2026-08-31T20:46:28.051Z - **Download time:** 771 ms - **Static scan time:** 3072 ms - **AI review time:** 62690 ms - **Total time:** 66535 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically changes the user's OpenCode instruction configuration. The added file tells agents that package directives are binding. - **Trigger:** npm install runs the postinstall hook. - **Impact:** Future OpenCode sessions load package-authored directives without an explicit setup command. - **Evidence paths:** package.json, scripts/bootstrap-agents-md.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-31T20:46:28.051Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent instruction and configuration mutation. - **Attack narrative:** The npm postinstall hook runs a script that creates or updates an OpenCode plugin instruction file, patches the user's global OpenCode configuration to load it, and inserts language asserting that its directives are binding. This changes a broad AI-agent control surface during dependency installation rather than through an explicit user setup action. - **Rationale:** This is an unconsented postinstall mutation of a broad AI-agent control surface. The automatic configuration change makes package-authored instructions load in later OpenCode sessions. - **Files touched:** ~/.config/opencode/plugins/omo-meta-governor/instructions.md, ~/.config/opencode/opencode.jsonc, ~/.config/opencode/AGENTS.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a bootstrap script after npm installation., The bootstrap targets the user's OpenCode configuration and instruction paths., It installs directives that claim to be binding instructions for agents., It writes the instruction path into the global OpenCode instructions array without an explicit user command. - **Evidence against:** The bootstrap contains an opt-out environment variable., No lifecycle self-dependency is declared in package.json., No network request is present in the install bootstrap. ## Public findings ### 1.
