Caveat verdict
tickflow
Reads local files AND makes external network calls
TickFlow Python SDK wrapper for stock/futures market data that reads TICKFLOW_API_KEY from env and queries tickflow.org; all behavior matches the stated market data retrieval 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.
Reads local files AND makes external network calls — the capabilities for data exfiltration co-occur (data-flow not verified)

Why the tier is capped
Execution sink present in raw bytes (Hard Floor: class A/E/F). Final tier capped at Caution — cannot be lifted by any downgrade, example-payload opt-in, or allowlist.
Permissions & capabilities
Requires 1 environment variable. (1 sensitive: TICKFLOW_API_KEY). Requires 2 system binaries.
