Caveat verdict
brave-shim
Receives external input AND executes processes
The skill uses a Python script to locate and overwrite OpenClaw's bundled JavaScript files (brave-web-search-provider*.js) to redirect Brave API endpoints to a local service, directly modifying the host application's installed code — unusual and broad capability well beyond its stated search-proxying purpose.
Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.
What it does
These are capability combinations: each listed behavior occurs in the skill, but Caveat detects co-occurrence — it does not verify that one flows into another. Read the code to confirm a live chain.

Why the tier is capped
Execution sink present in raw bytes (Hard Floor: class D/F). Final tier capped at Caution — cannot be lifted by any downgrade, example-payload opt-in, or allowlist.
