Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found a narrowly gated runtime migration in the global postinstall path and product-aligned runtime behavior. The flagged agent paths resolve to project/session data, while persistent service setup is presented as an explicit CLI action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-14T02:55:18.622Z - **Finished:** 2026-10-14T03:01:09.911Z - **Download time:** 1279 ms - **Static scan time:** 3572 ms - **AI review time:** 346437 ms - **Total time:** 351289 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:** No attack was identified. The install hook is restricted to global installs and its bridge only migrates an already adopted, completed runtime store to a newer version. - **Trigger:** A global npm install invokes the postinstall hook; the bridge proceeds only when its adoption and version checks pass. - **Impact:** No unconsented foreign agent configuration change, credential theft, or other concrete attack effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T03:01:09.911Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It stages a product runtime update and updates the version pointer. The inspected agent integration paths access project history, memory, and session data; service setup is offered as an explicit CLI command. - **Rationale:** Source inspection found a narrowly gated runtime migration in the global postinstall path and product-aligned runtime behavior. The flagged agent paths resolve to project/session data, while persistent service setup is presented as an explicit CLI action. - **Files touched:** package.json, scripts/install-bridge.cjs, dist/install-bridge.js, dist/history.js, dist/memory.js, dist/codex.js, dist/sdk.js, dist/directory-handlers.js, dist/git-handlers.js, dist/pi.js, dist/yeaft.js, dist/service.js, dist/cli.js, dist/config.js, dist/connection.js - **Network endpoints:** wss://msclaude.ai ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest’s postinstall invokes the bridge, while the hook runs it only for global npm installs., The bridge skips unless an existing version store is adopted and complete and the installed version is newer; it prepares a runtime migration for that store., The indicated Claude and Codex locations resolve to project history, project memory, and session directories, not global agent settings or plugin locations., The inspected runtime hints cover executable path lookup, work-directory file upload, Git status parsing, and local backend text or attachment handling., The service code selects user-level service artifact locations, and the CLI presents service installation as an explicit command., The configured relay defaults to the product service, and the connection sends a configured password as relay authentication. ## Affected versions and remediation This report applies to @agent-link/agent@0.1.339. - Review the evidence and your use of @agent-link/agent@0.1.339 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.
