## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 20 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.6.19
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. 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 implements a local runner that authenticates with WildCrane and launches a selected coding agent. The flagged credential handling is provider-specific local configuration, and the reviewed network calls use WildCrane endpoints with the runner session token.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 94.0%
- **Started:** 2026-11-04T02:27:13.735Z

- **Total time:** 56340 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 CLI connects to WildCrane and launches configured local coding agents, passing a selected provider key to the agent that uses it.

- **Trigger:** Invoking the wildcrane-runner CLI; the --settings option opens its local settings flow.

- **Impact:** The reviewed flows support the package's stated local-runner purpose; no unrelated credential transfer or other attack behavior was identified.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-04T02:28:10.075Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Runner session tokens authenticate requests to WildCrane services. Provider secrets are filtered by selected provider and supplied through the local agent process environment.

- **Rationale:** The package implements a local runner that authenticates with WildCrane and launches a selected coding agent. The flagged credential handling is provider-specific local configuration, and the reviewed network calls use WildCrane endpoints with the runner session token.

- **Files touched:** ~/.wildcrane/machine.json, ~/.wildcrane/session.json, ~/.wildcrane/settings.json

- **Network endpoints:** https://api.ai4kanban.dev, https://yajrbpprmdvtkvjjfpbk.supabase.co

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The prepare script runs the package build; no preinstall, install, or postinstall hook is declared., The CLI starts the runner or opens its settings flow when invoked., Provider secrets are selected for the chosen agent and passed to its environment., Cloud requests use the WildCrane API and Supabase endpoints.

- **Evidence against:** The key settings describe provider-specific keys as stored locally and only used by providers that need them., The secret assignment code filters settings by the selected provider before adding them to the spawned agent environment., Cloud API calls authenticate with the runner's session token; no provider key is included in the shown request flow.

## Affected versions and remediation

This report applies to wildcrane-runner@0.6.19.

- Review the evidence and your use of wildcrane-runner@0.6.19 before allowing it. Restrict the permissions described in this report.
