A developer discovered a critical flaw in their commit message generation tool, MCP, which failed to handle empty diffs gracefully. Unlike a standalone script that correctly raises an error for empty staged changes, the MCP tool would pass the empty diff to an AI model, resulting in a nonsensical commit message like "There are no staged or unstaged changes in the repository." This sentence, when piped directly into `git commit -m`, would be committed as actual code, a worse outcome than the script's explicit failure. The developer has since implemented a fix by adding the same guard clause from the script to the MCP tool. AI
