An unconsented package can influence future AI-agent behavior outside the consumer project. - **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:** 0.40.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically modifies OpenCode's agent instruction control surface. It inserts mandatory package-authored directives and registers them in the user's OpenCode configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-31T22:09:12.357Z - **Finished:** 2026-08-31T22:10:05.326Z - **Download time:** 501 ms - **Static scan time:** 2972 ms - **AI review time:** 49493 ms - **Total time:** 52969 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically modifies OpenCode's agent instruction control surface. It inserts mandatory package-authored directives and registers them in the user's OpenCode configuration. - **Trigger:** npm installation, through the postinstall lifecycle hook. - **Impact:** An unconsented package can influence future AI-agent behavior outside the consumer project. - **Evidence paths:** package.json, scripts/bootstrap-agents-md.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-31T22:10:05.326Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes agent instructions and patches OpenCode configuration. - **Attack narrative:** On npm installation, package.json launches the bootstrap script. That script creates or edits an OpenCode plugin instruction file containing directives described as binding, then adds that file to the user's OpenCode instructions configuration. This is an automatic mutation of a broad AI-agent control surface rather than an explicit user-command setup. - **Rationale:** The postinstall hook unconsentedly persists mandatory package instructions into OpenCode's configuration. This concrete agent-control mutation warrants blocking. - **Files touched:** ~/.config/opencode/plugins/omo-meta-governor/instructions.md, ~/.config/opencode/AGENTS.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 bootstrap script after installation., The bootstrap targets the OpenCode configuration and plugin instruction files in the user's home directory., The installed instruction text declares package directives binding and mandatory., The bootstrap adds its instruction file to OpenCode's instructions array and rewrites the configuration file. - **Evidence against:** No runtime dependency on this package's own name is declared., No credential collection or network exfiltration was confirmed in the install hook. ## Public findings ### 1.
