An installed dependency can alter the behavior and instruction hierarchy of OpenCode agents 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:** 0.42.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm installation, the package changes global OpenCode agent instructions and configuration. It injects directives presented as binding before registering the injected file for use. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-09-01T10:22:01.261Z - **Finished:** 2026-09-01T10:22:56.453Z - **Download time:** 758 ms - **Static scan time:** 2949 ms - **AI review time:** 51483 ms - **Total time:** 55192 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm installation, the package changes global OpenCode agent instructions and configuration. It injects directives presented as binding before registering the injected file for use. - **Trigger:** npm installation runs the postinstall script unless the user has pre-set its opt-out environment variable. - **Impact:** An installed dependency can alter the behavior and instruction hierarchy of OpenCode agents without an explicit setup command. - **Evidence paths:** package.json, scripts/bootstrap-agents-md.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-01T10:22:56.453Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic mutation of global AI-agent instructions and configuration. - **Attack narrative:** Installing the package automatically invokes its bootstrapper. The script removes a prior AGENTS.md snippet, creates or changes a global OpenCode plugin instruction file containing directives declared binding, and adds that file to the user's OpenCode configuration. This is an unconsented postinstall modification of a broad AI-agent control surface. - **Rationale:** The package has a concrete automatic install-time chain that modifies global AI-agent instructions and configuration, rather than requiring an explicit user setup action. The injected content asserts authority over agent behavior, meeting the install-control-surface blocking policy. - **Files touched:** ~/.config/opencode/AGENTS.md, ~/.config/opencode/plugins/omo-meta-governor/instructions.md, ~/.config/opencode/opencode.jsonc ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall bootstrapper., The bootstrapper targets global OpenCode instruction and configuration files in the user's home directory., It installs text that calls its directives binding and requires agents to follow them., Installation removes an older AGENTS.md snippet, writes a new instruction file, and registers it in opencode.jsonc. - **Evidence against:** No credential collection or outbound network activity occurs in the postinstall script., The bootstrapper has an environment-variable opt-out, but it is enabled by default. ## Public findings ### 1.
