Core reference
Keep this reference beside a real task. Commands and syntax are more durable when each entry is attached to a concrete purpose and expected result.
identify → change → verifyCommon patterns
Use small, explicit patterns first. Confirm inputs and outputs before combining operations into larger workflows.
- Inspect the current state
- Make one focused change
- Verify the result
- Record the useful command or pattern
Debugging checklist
When a result differs from expectation, reduce the example, inspect the exact input, and use the tool output as evidence rather than guessing.
