wildcrane-runner@0.4.0
WildCrane's Local Runner — connects this computer to WildCrane and runs its jobs on your local Claude Code, Codex, OpenCode or Cursor.
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package’s network and process activity matches its disclosed purpose: connecting a user’s local agent tools to WildCrane tasks. The flagged credential and shell references did not reveal automatic exfiltration or unrelated execution.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
A user invokes the wildcrane-runner command; the runner signs in if needed, connects to WildCrane, and runs assigned jobs through a local agent tool.
Impact
Observed network access, process execution, and local state writes serve the package’s disclosed runner and update functions.
Mechanism
It contacts WildCrane and npm for service tasks and runner updates, and launches the selected local agent with the inherited environment. Updates are checked against registry integrity metadata.
AI rationale
The package’s network and process activity matches its disclosed purpose: connecting a user’s local agent tools to WildCrane tasks. The flagged credential and shell references did not reveal automatic exfiltration or unrelated execution.

Decision evidence
public snapshotAI called this Clean at 97.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package describes itself as connecting to WildCrane and running its jobs through local Claude Code, Codex, OpenCode, or Cursor.
- The README says the runner signs in through a browser on first start and updates to the version WildCrane names.
- The launcher verifies downloaded runner tarballs against the npm registry’s SHA-512 integrity value before installing them.
- The runner passes the environment to the selected local agent harness to carry out the requested task.
Evidence against
- The credential-related references are provider settings and environment passed to local agent tools; I found no flow sending discovered credentials to an unrelated host.
- The curl-to-shell strings are installer commands for supported agent tools, not automatic startup or install actions.
- The prepare script invokes a build command; no install-time data collection or unrelated network contact was identified.
