This can mutate broad AI-agent control surfaces in the consumer environment during package installation. - **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:** 0.2.1 - **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. Installation automatically runs an external platform binary to configure AI-agent integration surfaces. No user command or affirmative setup choice is required. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-28T09:14:19.526Z - **Finished:** 2026-09-28T09:15:05.957Z - **Download time:** 250 ms - **Static scan time:** 33 ms - **AI review time:** 46146 ms - **Total time:** 46431 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:** Installation automatically runs an external platform binary to configure AI-agent integration surfaces. No user command or affirmative setup choice is required. - **Trigger:** npm postinstall execution. - **Impact:** This can mutate broad AI-agent control surfaces in the consumer environment during package installation. - **Evidence paths:** package.json, npm/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-28T09:15:05.957Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script resolves a platform binary and runs its setup command; the stated setup covers skills, hooks, MCP wiring, and an AGENTS file. - **Attack narrative:** The package activates at postinstall and launches a platform-specific binary. It then runs setup by default, with only an environment-variable opt-out. The source states that setup configures skills, hooks, MCP wiring, and an AGENTS file, which are AI-agent control surfaces. Because this occurs automatically and the actual setup implementation is outside the inspected JavaScript snapshot, the install path creates an unconsented broad control-surface mutation risk. - **Rationale:** An automatic postinstall invokes opaque setup that targets multiple AI-agent configuration surfaces. This is concrete unconsented install-time agent control-surface mutation. ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package registers a postinstall lifecycle hook., The hook automatically invokes a resolved platform binary with the setup command unless an environment opt-out is already set., The setup is described as installing skills, hooks, MCP wiring, and an AGENTS file during installation., The invoked implementation is a platform optional-dependency binary, so its setup mutations are not inspectable in this package snapshot. ## Affected versions and remediation This report applies to @einsia/agent-git@0.2.1. - Avoid installing @einsia/agent-git@0.2.1. 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.

High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** npm/postinstall.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = @einsia/agent-git@0.9.0 matchedIdentity = npm:QGVpbnNpYS9hZ2VudC1naXQ:0.9.0 similarity = 0.500 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 10. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The package registers a postinstall lifecycle hook.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** npm/postinstall.js - **Public source:** [View source]() The hook automatically invokes a resolved platform binary with the setup command unless an environment opt-out is already set. Public source snippet (untrusted): ```javascript if (truthy(process.env.AGIT_SKIP_SETUP)) return; const setup = spawnSync(bin, ['setup'], { stdio: 'inherit', env }); if (setup.status !== 0) { log.warn('`agit setup` ``` ### 12.

Public source snippet (untrusted): ```javascript // 1. Self-check that the binary really runs (an architecture mismatch, Rosetta and the like // surface here rather than the first time the user types agit). // 2. Run `agit setup` — the product promise of "installed by default at download time": // skills, hooks, MCP and AGENTS.md, all in one go.
