From 3e5e5974c4a96882e20cbc628a5a83bb5861d4d1 Mon Sep 17 00:00:00 2001 From: CleverThis Date: Tue, 14 Apr 2026 09:43:56 +0000 Subject: [PATCH 1/3] test(cli): validate docstring examples respect positional order Implemented DocstringExampleValidator class in src/cleveragents/cli/docstring_validator.py that validates CLI command docstring examples to ensure positional arguments precede option flags and align with Typer signatures. Added Behave feature file at features/cli_docstring_example_validation.feature containing scenarios for valid and invalid docstring examples and edge cases. Added step definitions at features/steps/cli_docstring_example_validation_steps.py implementing Given/When/Then steps to drive validation and report mismatches. Fixed the problematic docstring in src/cleveragents/cli/commands/plan.py (rollback_plan function) to reflect correct positional argument order and clearer usage. The validator ensures that docstring examples have positional arguments before option flags, matching the actual Typer command signature.
