WHAT IT DOES

What cribl_commitPipeline does on Cribl

AI agents use cribl_commitPipeline to create or update resources in Cribl — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Cribl environment.

WHY IT NEEDS A POLICY

Why cribl_commitPipeline needs a policy

This tool creates a permanent record (commit) in version control, which is a Write operation. While commits are theoretically reversible via revert operations, committing configuration changes represents a state modification.

From the tool's definition Tool description states it 'Commits staged pipeline config changes to version control' — a write operation that modifies version control history. The ability to commit changes is reversible (commits can be reverted) and does not permanently delete data.
