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 process execution, network requests, and settings writes are tied to explicit installer use or the pi extension’s language-server feature. Credential flows inspected were for router validation or user-initiated provider login through the provider’s OAuth endpoints. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-30T22:16:10.857Z - **Finished:** 2026-10-30T22:16:47.910Z - **Download time:** 620 ms - **Static scan time:** 345 ms - **AI review time:** 36087 ms - **Total time:** 37053 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 package configures AI clients to route through Weave Router. - **Trigger:** Explicit CLI installation or use of the pi extension’s language-server feature. - **Impact:** These actions support the package’s stated purpose. No unrelated data collection or unauthorized account action was found. - **Review source:** ai\_review - **Reviewed:** 2026-10-30T22:16:47.910Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer validates a router key with the selected router and writes client configuration; pi can spawn a configured language server. - **Rationale:** The package has no install lifecycle hook, and its process execution, network requests, and settings writes are tied to explicit installer use or the pi extension’s language-server feature. Credential flows inspected were for router validation or user-initiated provider login through the provider’s OAuth endpoints. - **Files touched:** .claude/settings.json, .claude/settings.local.json, .codex/config.toml, opencode.json, .pi/models.json, .pi/settings.json - **Network endpoints:** router.workweave.ai, claude.ai, console.anthropic.com, auth.openai.com ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The only npm lifecycle script is prepack; there is no install, preinstall, or postinstall hook., The CLI selects install.sh or uninstall.sh based on an explicit command invocation., The Windows installer takes a Weave Router key from its configured sources and validates it against the selected router URL., The Windows installer writes settings for the selected client, and the pi language-server process launcher is part of an explicit extension feature. - **Evidence against:** Installer network calls and configuration writes serve the package’s stated routing setup purpose., The inspected credential enrollment flow uses explicit login commands and the corresponding provider’s OAuth endpoints., No default account action, unrelated credential transfer, or concealed automatic execution was identified. ## Affected versions and remediation This report applies to @workweave/router@0.2.30. - Review the evidence and your use of @workweave/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.
