What the code does
What does this mean?
These are capabilities our static analysis found in the latest published version. They describe what the code can do, not whether it is malicious: many tools need shell access or the network to do their job. Use them to decide what to check before installing.
- Starts other processes Code that launches separate programs.
- Sends data to outside servers Code that posts data to network addresses.
Having a capability is not wrongdoing; many tools need these to do their job. It tells you what to check before you install.
This is public metadata, not a safety certification or complete assessment. Static analysis cannot establish what a tool does at runtime.
