+description: Use when creating git commits to ensure commit messages follow project standards. Applies the 7 rules for great commit messages with focus on conciseness and imperative mood.
+---
+
+# Git Commit Guidelines
+
+Follow these rules when creating commits for this repository.
+
+## The 7 Rules
+
+1. **Separate subject from body with a blank line**
+2. **Limit the subject line to 50 characters**
+3. **Capitalize the subject line**
+4. **Do not end the subject line with a period**
+5. **Use the imperative mood** ("Add feature" not "Added feature")
+6. **Wrap the body at 72 characters**
+7. **Use the body to explain what and why vs. how**
+
+## Key Principles
+
+**Be concise, not verbose.** Every word should add value. Avoid unnecessary details about implementation mechanics - focus on what changed and why it matters.
+
+**Subject line should stand alone** - don't require reading the body to understand the change. Body is optional and only needed for non-obvious context.
+
+**Focus on the change, not how it was discovered** - never reference "review feedback", "PR comments", or "code review" in commit messages. Describe what the change does and why, not that someone asked for it.
+
+**Avoid bullet points** - write prose, not lists. If you need bullets to explain a change, you're either committing too much at once or over-explaining implementation details.
+
+## Format
+
+Always use a HEREDOC to ensure proper formatting:
+
+```bash
+git commit -m "$(cat <<'EOF'
+Subject line here
+
+Optional body paragraph explaining what and why.
+EOF
+)"
+```
+
+## Good Examples
+
+```
+Add session isolation for concurrent executions
+```
+
+```
+Fix encoding parameter handling in file operations
+
+The encoding parameter wasn't properly passed through the validation
+layer, causing base64 content to be treated as UTF-8.
+```
+
+## Bad Examples
+
+```
+Update files
+
+Changes some things related to sessions and also fixes a bug.
+```
+
+Problem: Vague subject, doesn't explain what changed
+
+```
+Add file operations support
+
+Implements FileClient with read/write methods and adds FileService
+in the container with a validation layer. Includes comprehensive test
+coverage for edge cases and supports both UTF-8 text and base64 binary
+encodings. Uses proper error handling with custom error types from the
+shared package for consistency across the SDK.
+```
+
+Problem: Over-explains implementation details, uses too many words
