This is crucial for accurately summarizing the changes. - -### Step 3: Propose the Commit Message - -- Based on the collected diff, formulate a commit message. The message **MUST** be presented to the USER in a markdown block for review before committing. -- When referencing file changes in a commit body, **MUST** use the filename only (e.g., `McpUtils.cs`), not the full path (e.g. `cci:7://file:///c:/mcp-unity/Editor/Utils/conventional-commits.md:0:0-0:0`). - -#### Structuring the Commit - -**For commits containing a single, focused change:** -- Use a standard, single-line header. -- The body is optional and should only be used for significant explanations. - -**For commits containing multiple, logically distinct changes:** -- The header **MUST** list each distinct change on a separate line.
