A future OpenCode launch loads the package-controlled plugin from the user's global configuration. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.0.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. An automatic npm postinstall modifies the user's global OpenCode CLI configuration and registers this package as a plugin. This creates an unconsented AI-agent control-surface change. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-22T03:48:01.864Z - **Finished:** 2026-09-22T03:48:38.999Z - **Download time:** 758 ms - **Static scan time:** 47 ms - **AI review time:** 36329 ms - **Total time:** 37135 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** An automatic npm postinstall modifies the user's global OpenCode CLI configuration and registers this package as a plugin. This creates an unconsented AI-agent control-surface change. - **Trigger:** Installing the package through npm triggers postinstall. - **Impact:** A future OpenCode launch loads the package-controlled plugin from the user's global configuration. - **Evidence paths:** package.json, scripts/install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-22T03:48:38.999Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer creates a package-controlled plugin copy, appends its directory to cli.json plugins, and writes the configuration. - **Attack narrative:** npm installation automatically invokes scripts/install.mjs. It copies plugin files into the OpenCode configuration directory, adds the copied directory to the global plugins list in cli.json, and writes that configuration. OpenCode can then load the package plugin on later launches without an explicit setup command. - **Rationale:** The package uses an automatic postinstall hook to mutate a global AI-agent plugin control surface. This is concrete unconsented persistence into OpenCode configuration, so it meets the install-control-surface block policy. - **Files touched:** scripts/install.mjs, package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs its installer after npm installation., The installer adds its target directory to the global OpenCode CLI plugins list., The installer writes the modified global CLI configuration to disk. - **Evidence against:** The runtime usage request sends the API key only to the OpenCode usage endpoint. ## Affected versions and remediation This report applies to @leo.gimp/opencode-usage-bar@2.0.0. - Avoid installing @leo.gimp/opencode-usage-bar@2.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
