Does Spec Updater overwrite my existing spec files?

No, it performs atomic, in-place updates that preserve your existing Markdown structure and only modify the specific sections or items requested.

Can I add notes to a phase that is already completed?

Yes, the add-implementation-notes operation can append notes to any existing phase identified in the spec file, even if it is already marked as complete.

Can I update multiple things at once?

Yes, the batch-update operation allows you to change a phase status, check off all relevant tasks, and add implementation notes in a single efficient operation.

What format does the spec file need to be in?

The skill works with standard Markdown files using common patterns like '### Phase' headers, bold status lines, and standard GFM task lists (- [ ]).

Is task matching case-sensitive?

No, task matching is case-insensitive and uses substring matching, so you only need to provide enough unique text to identify the task you want to check off.

生産性とワークフロー

Automates project progress tracking by updating specification files with status changes, task completions, and implementation notes.

概要

The Spec Updater skill streamlines the development lifecycle by programmatically synchronizing implementation progress with project documentation. It allows Claude to mark milestones as complete, check off specific tasks using substring matching, and append detailed implementation notes directly into Markdown-based spec files. This ensures that project specifications remain accurate 'living documents' without requiring manual updates, facilitating better visibility for team members and supporting structured multi-phase development sessions.
