Summary

  • Fix CLI shape mismatch: completion zshcompletion generate [shell]
  • Update uninstall behavior: confirmation prompt now cancels entire operation if declined
  • Fix "not installed" uninstall exit code: 0 → 1
  • Update shell detection error message to match actual implementation
  • Replace Purpose placeholder with actual description

Test plan

  • openspec validate cli-completion passes
  • Verified spec matches implementation via code review

✏️ Tip: You can customize this high-level summary in your review settings.

Update the cli-completion spec to match the actual implementation:

- Change `completion zsh` to `completion generate [shell]` command structure
- Update uninstall behavior to reflect confirmation prompt cancels entire operation
- Change "not installed" uninstall exit code from 0 to 1
- Update shell detection error message to match implementation
- Replace Purpose placeholder with actual description

Walkthrough

The CLI completion specification is restructured from a zsh-specific command pattern to a shell-agnostic generate [shell] subcommand approach. Changes include updated error handling for shell auto-detection, expanded uninstall flows with user confirmations, and revised examples reflecting the new command structure.

Changes

Cohort / File(s) Summary
CLI Completion Specification
openspec/specs/cli-completion/spec.md
Updated purpose and command structure from zsh-specific to generic generate [shell] subcommand. Modified scenario expectations for generating completions via stdout. Expanded uninstall flows with confirmation prompts and updated cancellation messaging. Revised error handling for failed shell auto-detection. Updated all examples and guidance to use the new generate-based command pattern. Shifted to shell-agnostic approach with explicit shell parameterization.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

  • Command structure consistency: Verify that the generate [shell] pattern is uniformly applied across all scenarios, examples, and guidance sections.
  • Error handling alignment: Confirm shell auto-detection failure messages and usage hints are clear and actionable.
  • Uninstall flow coherence: Review confirmation prompts, cancellation paths, and removal behavior to ensure they provide appropriate user safeguards.
  • Example completeness: Ensure all code examples, particularly redirection guidance, correctly reflect the new command structure.

Poem

🐰✨ A completion so fine, now shell-agnostic in design!
No more zsh alone—the generate command's grown,
With shells of choice and prompts to rejoice,
This spec takes flight, refactored just right! 🎉

4-4: Purpose text now provides clear, implementation-relevant description.

The placeholder has been replaced with a substantive description that covers current functionality (Zsh support), intended scope (shell completion for CLI), and future extensibility. Improves spec clarity.


33-35: Command structure correctly reflects shell-agnostic generate pattern.

The subcommand list now uses the unified [shell] parameterization across generate, install, and uninstall operations. Descriptions accurately convey both auto-detection and explicit shell specification behaviors. Consistent with command examples throughout the spec (lines 60, 244).


58-66: Completion generation scenario correctly specifies the new generate subcommand.

The command example at line 60 uses the new openspec completion generate zsh form, and the scenario clearly specifies stdout output. Requirements for completions content (lines 62-65) are comprehensive and remain unaffected by the command structure change.


142-149: Uninstall flow now explicitly specifies confirmation and cancellation behavior.

The scenario now includes three key additions: (1) confirmation prompt requirement before proceeding (line 143), (2) explicit cancellation message and exit when user declines (line 144), and (3) conditional file removal based on detected setup (lines 145-147). This directly implements the PR objective that declining the prompt cancels the entire uninstall operation, preventing any file or config modifications.


156-160: Exit code correctly changed to 1 for "not installed" error case.

Line 160 now specifies exit code 1 for the case where completion is not installed, correctly treating it as an error condition. This is consistent with other error scenarios in the spec (lines 214, 234) and appropriately differentiated from success cases (line 134). The error message at line 159 is clear and implementation-relevant.


229-234: Shell detection error message updated with clear guidance.

The "Shell not detected" scenario now provides two pieces of helpful error information: (1) a clear error message at line 232 explaining that auto-detection failed and requesting explicit specification, and (2) a usage hint at line 233 showing the correct command syntax. This is appropriately distinguished from the "Non-Zsh shell detection" scenario (lines 49-52) which handles the case of detected but unsupported shells.


244-244: Output format example consistent with updated command structure.

The redirection example at line 244 uses the new openspec completion generate zsh form, maintaining consistency with the generation scenario (line 60) and the command structure definition (line 33). No inconsistencies with the updated command pattern detected throughout the document.


1-287: Specification adheres to normative language guidelines.

The spec consistently uses "SHALL" in Requirement headers for normative requirements (lines 8, 27, 39, 56, 101, 138, 164, 208) and applies clear conditional language in Scenario sections using BDD-style WHEN/THEN/AND patterns. No detected violations of the guideline to avoid "should/may" in normative contexts.
