What problem does it solve? Updating a single entry in a large deduplicated Markdown catalog table by hand risks overwriting untouched columns or breaking table formatting. This Skill merges a partial patch into one existing row of the catalog master table while preserving all other columns. ## Core Features & Use Cases - In-place row patching: Supply an id and a partial patch object; only the provided keys change while id, uid, and all other columns are preserved. - Dry-run preview: Set dryRun to true to inspect the before/after JSON and a git diff preview without writing to disk. - Automatic timestamping: The updated column is bumped to the current second-accurate ISO timestamp unless explicitly overridden. - Use Case: Bump the version and popularity of the claude entry by patching {"version": "2.0.31", "popularity": "141k★"} without touching its vendor, license, or URL fields. ## Quick Start Ask the AI to patch the catalog entry with id claude, setting version to 2.0.31, using the edit-catalog skill with a dry run first.
