Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The global install hook can stage and activate a newer runtime when prior adoption is complete, so the guarded lifecycle capability warrants a warning. The flagged agent integration locations inspected access session and project-memory paths and did not establish broader agent configuration mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-12T09:02:45.563Z - **Finished:** 2026-10-12T09:03:27.771Z - **Download time:** 1773 ms - **Static scan time:** 2652 ms - **AI review time:** 37782 ms - **Total time:** 42208 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:** A guarded global-install migration can fetch and stage a runtime and switch the active version pointer. The inspected code did not establish an unconsented attack. - **Trigger:** Global npm installation when a completed version-store adoption exists and the package version is newer. - **Impact:** The migrated AgentLink runtime may be replaced with the validated package version. - **Evidence paths:** package.json, scripts/install-bridge.cjs, dist/install-bridge.js, dist/runtime-release.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T09:03:27.771Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall bridge fetches a runtime manifest, prepares a bundle, and updates the version pointer; manifest overrides are restricted to loopback. - **Rationale:** The global install hook can stage and activate a newer runtime when prior adoption is complete, so the guarded lifecycle capability warrants a warning. The flagged agent integration locations inspected access session and project-memory paths and did not establish broader agent configuration mutation. - **Files touched:** package.json, scripts/install-bridge.cjs, dist/install-bridge.js, dist/runtime-release.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The npm postinstall runs an installer bridge; that hook runs its migration only for global installs., The bridge skips unless version-store adoption is complete and the package version is newer, then stages a runtime and updates its version pointer., A manifest URL override must be loopback, and the manifest validates supported package, platform, architecture, and bundle fields., The Codex and Claude integration locations inspected resolve session and project-memory paths; they do not show config mutation., Service persistence is exposed through an explicit CLI service install command. - **Evidence against:** A global npm postinstall can fetch and stage a package runtime and modify the active version pointer when migration conditions are met. ## Affected versions and remediation This report applies to @agent-link/agent@0.1.338. - Review the evidence and your use of @agent-link/agent@0.1.338 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
