It installs binding instructions and registers them in OpenCode configuration. - **Trigger:** npm installation runs the postinstall hook automatically. - **Impact:** A package can impose its own instructions on future AI-agent sessions without an explicit setup command. - **Evidence paths:** package.json, scripts/bootstrap-agents-md.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-05T05:41:20.212Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic home-directory OpenCode configuration and instruction injection. - **Attack narrative:** On installation, npm launches the bootstrap script. The script writes a package-authored instruction file under the user's OpenCode configuration, injects text asserting its directives are binding, and registers that file in opencode.jsonc. This modifies a broad AI-agent control surface automatically rather than through an explicit user setup action. - **Rationale:** This is an unconsented postinstall mutation of a foreign AI-agent control surface, with injected instructions intended to control agent behavior. That meets the install-hook abuse blocking policy. - **Files touched:** package.json, scripts/bootstrap-agents-md.mjs, ~/.config/opencode/plugins/omo-meta-governor/instructions.md, ~/.config/opencode/opencode.jsonc, ~/.config/opencode/AGENTS.md ### 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 program after installation., The bootstrap creates and writes an OpenCode plugin instruction file in the user's home configuration., The injected text declares package directives binding and says agents must follow them., The bootstrap adds that instruction file to the user's OpenCode configuration without an explicit command. - **Evidence against:** The manifest has no runtime dependency on another release of this package., The inspected installer contains no credential collection or network transmission. ## Public findings ### 1.
