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 CLI performs setup when explicitly run. Reviewed credential use is directed to the configured router, while the flagged process execution supports language-server transport. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-11-02T01:47:25.848Z - **Finished:** 2026-11-02T01:48:00.046Z - **Download time:** 510 ms - **Static scan time:** 323 ms - **AI review time:** 33364 ms - **Total time:** 34198 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 installs and configures Weave Router integrations when a user runs its CLI. - **Trigger:** Explicit CLI invocation; pi extension behavior is triggered when a host loads the extension. - **Impact:** Expected setup and routing behavior for the selected client; no unauthorized credential transfer or other attack behavior was found. - **Review source:** ai\_review - **Reviewed:** 2026-11-02T01:48:00.046Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer reads or prompts for a router key, contacts the configured router for setup and validation, writes selected client configuration, and can spawn configured language servers. - **Rationale:** The package has no install lifecycle hook, and its CLI performs setup when explicitly run. Reviewed credential use is directed to the configured router, while the flagged process execution supports language-server transport. - **Files touched:** ~/.claude/settings.json, ~/.claude/settings.local.json, ~/.codex/config.toml, ~/.config/opencode/opencode.json - **Network endpoints:** router.weaveos.com, router.workweave.ai ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares CLI entry points and a pi extension, with no install, preinstall, or postinstall hook., The CLI opens the hosted setup page only when invoked with no arguments; otherwise it runs the installer., The installer’s client event reports use the configured router endpoint and a trust gate; the key is sent in a protected header file., The off-state event is called from the explicit \`off\` command path., The Windows installer prompts for a Weave Router key or reads its designated environment/config value, then configures the selected client., LSP process spawning uses shell:false and is part of the language-server transport. - **Evidence against:** The package includes shell and process execution, filesystem writes, and network requests, but these appear tied to explicit installation, configuration, routing, or language-server features., The \`prepack\` script is a packaging-time helper, not an install lifecycle hook. ## Affected versions and remediation This report applies to @weave-os/router@0.2.34. - Review the evidence and your use of @weave-os/router@0.2.34 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.
