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. The package has no install lifecycle hook, and its flagged process and network behavior matches its documented router installer and LSP purpose. Credentials are obtained for the router and sent to the configured router endpoint during explicit setup. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-30T22:15:58.510Z - **Finished:** 2026-10-30T22:16:36.223Z - **Download time:** 508 ms - **Static scan time:** 346 ms - **AI review time:** 36858 ms - **Total time:** 37713 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 reviewed capabilities support the router installer and configured LSP integration. - **Trigger:** The installer and uninstaller run after explicit CLI invocation; LSP spawning occurs when the extension starts a configured language server. - **Impact:** No unauthorized credential transfer, account action, persistence, or destructive behavior was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-30T22:16:36.223Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer validates a router key against the configured router URL and writes selected client settings; the LSP transport launches its configured command without a shell. - **Rationale:** The package has no install lifecycle hook, and its flagged process and network behavior matches its documented router installer and LSP purpose. Credentials are obtained for the router and sent to the configured router endpoint during explicit setup. - **Files touched:** .claude/settings.json, .codex/config.toml, opencode.json, providers.json, models.json - **Network endpoints:** router.workweave.ai, user-configured router base URL ### Review decision - **Verdict:** Clean - **Confidence:** 97.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares only a prepack script, with no install, postinstall, or preinstall hook., The CLI opens the setup page only when a user invokes it without arguments; otherwise it runs the installer., The Windows installer gets a router key from an environment variable, installed config, or user prompt, then probes the configured router URL., The installer writes the router key into the selected client’s provider configuration as setup requires., The LSP process launcher uses shell:false and is explicitly a transport for a configured language server., Install state-change reporting sends only an action and client name to the configured router endpoint. - **Evidence against:** The package includes network access, process execution, and configuration writes, but these are part of its user-invoked router setup and LSP functions. ## Affected versions and remediation This report applies to @weave-os/router@0.2.30. - Review the evidence and your use of @weave-os/router@0.2.30 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.
