The downloaded runtime is executed for self-checking and later selected by the launcher. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 88.0% - **Started:** 2026-08-06T14:54:00.847Z - **Finished:** 2026-08-06T14:55:07.052Z - **Download time:** 505 ms - **Static scan time:** 1825 ms - **AI review time:** 63875 ms - **Total time:** 66205 ms ## Security analysis ### Published attack-surface review - **Summary:** A global postinstall can update an already-adopted AgentLink runtime and refresh its package-owned launcher. The downloaded runtime is executed for self-checking and later selected by the launcher. - **Trigger:** Global npm installation after the user has previously adopted the AgentLink version store. - **Impact:** A compromise of the allowed runtime publisher could execute a replacement AgentLink runtime in an already opted-in local agent installation. - **Evidence paths:** package.json, scripts/install-bridge.cjs, dist/install-bridge.js, dist/runtime-release.js, dist/version-stager.js, dist/launcher-manager.js, dist/service.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T14:55:07.052Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote runtime download, staging, self-check execution, and AgentLink launcher update. - **Rationale:** This is a real first-party agent lifecycle and persistence capability with install-time remote runtime execution, but it is guarded by prior adoption and limited to AgentLink-owned state. Source inspection found no concrete malicious chain or foreign/broad AI-agent control-surface mutation. - **Files touched:** scripts/install-bridge.cjs, dist/install-bridge.js, dist/runtime-release.js, dist/version-stager.js, dist/launcher-manager.js, ~/.agentlink/versions, ~/.agentlink/launcher/launcher.cjs - **Network endpoints:** https://msclaude.ai/files/agent/runtime/, wss://msclaude.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall via scripts/install-bridge.cjs., Global install calls prepareInstalledVersionBridge when a prior version-store adoption exists., dist/runtime-release.js downloads a runtime manifest and .tgz from https://msclaude.ai., The manifest supplies both bundle URL and integrity; no embedded signing key or signature verification is present., dist/version-stager.js executes the downloaded bundle's CLI self-check before staging it., dist/launcher-manager.js installs a persistent launcher under the package-owned AgentLink home. - **Evidence against:** The install bridge is skipped unless an existing adoption state, current version, and last-known-good version validate., Runtime URLs are restricted to msclaude.ai runtime paths (or loopback overrides)., Bundles have size, SHA-1, SHA-512, archive-shape, and package identity checks., Service persistence is exposed through explicit agentlink-client service install/uninstall commands., No source evidence of credential harvesting, unrelated file collection, or writes to Claude/Codex/Copilot control files. ## Public findings ### 1.
