# Task 2: mycmd Completion Improvement

## Goal
Enhance `mycmd` to capture all possible completion cases, ensuring robust, context-aware, and user-friendly completions.

## Test-Driven Approach
- For each improvement, write or update a test in `test/test.mycmd` before implementing the change.
- Use the test suite to verify that new completion scenarios are covered and regressions are prevented.
- Document each new test case and its expected outcome.

## Numbered Tasks
16. Audit all current mycmd methods and parameters for completion coverage.
17. Add completion for all method parameters, including optional and default values.
18. Ensure file, directory, and user completions are integrated where appropriate.
19. Test completion for edge cases (empty input, invalid input, partial matches).
20. Add custom completions for complex parameters (if needed).
21. Document all completion behaviors in the wiki.
22. Add/expand tests in `test/test.mycmd` to cover new completion scenarios.

## How to Test
- Run `bash test/test.mycmd` after each change.
- Ensure all test cases pass and new scenarios are covered.
- Use automated checks to detect infinite loops or hangs (see mitigation below).

## Mitigation for Interactive Hangs
- Add timeouts to test scripts using `timeout` or similar tools.
- Ensure all test cases are non-interactive and provide default/mock input where needed.
- Use CI or local scripts to kill tests that exceed a reasonable execution time.
