generate-commit-message

The generate-commit-message skill is an automated tool designed for software engineers to streamline version control workflows by ensuring commit history remains standardized and descriptive. By integrating directly with the Git staging area, this tool analyzes the current diff—excluding non-relevant meta-information—to synthesize a human-readable summary of code modifications. It specifically adheres to the Conventional Commits specification, enforcing a strict structure that includes a type, an optional scope, and a concise imperative description. This helps maintain a clean, navigable commit history that is vital for long-term project maintenance and automated changelog generation.

• Automatically captures staged code changes using the git --no-pager diff command for processing.

• Enforces Conventional Commits standards with support for types such as feat, fix, docs, style, refactor, perf, test, build, and ci.

• Limits commit message titles to 50 characters to ensure readability in terminal logs and git graphical interfaces.

• Implements an imperative mood requirement for the description to ensure clear communication of intent.

• Reduces manual overhead for developers who frequently manage complex repositories and need to quickly document incremental changes.

• The primary input is the staged set of changes within a local git repository; the output is a single, plain-text commit message.

• Ensure that files are properly staged (git add) before invoking the agent to ensure accurate diff analysis.

• The tool ignores colors in the diff output to prevent parsing errors and maintains consistency regardless of terminal theme settings.

• While the tool suggests a message based on content, it is designed for efficiency; ensure the context of the changes is reflected accurately in the diff before generation.

• Constraints include a maximum character limit and a fixed format, which ensures compatibility with CI/CD pipelines and automated release tools.
