- Rename setup-dev-env to adk-setup and git-ops to adk-git for consistency.

- Update adk-setup skill to use parallel tests and remove internal tool references.

- Update adk-git skill to include pre-commit checks and guidelines for detailed commit messages.

+### Detailed Commit Messages
+
+Promote detailed commit messages by including a short, concrete explanation in the body:
+- For **features**: Give a sample usage or explain the new capability.
+- For **fixes**: Explain what caused the error and how the fix addresses it.
+
+**Example (Feature):**
+```
+feat(workflow): Support JSON string parsing in schema validation
+
+Automatically parse JSON strings into dicts or Pydantic models when input_schema or output_schema is defined on a node.
+```
+
+**Example (Fix):**
+```
+fix(sessions): Prevent duplicate events when resuming HITL
+
+The interrupt_id was not checked before appending, causing duplicates if the user resumed multiple times. Added a check to ignore already processed interrupts.
+```
+
+Self-check before committing: read your subject line and ask "does this tell me _why_ someone made this change?" If it only describes _what_ changed, rewrite it.
 
 ### Rules
 
 1. **Imperative mood** - "Add feature" not "Added feature".
 2. **Capitalize** first letter of description (for release-please changelog).
 3. **No period** at end of subject line.
 4. **50 char limit** on subject line when possible, max 72.
-5. **Use body for context** - Add a blank line then explain *why*,

+## Pre-commit Hooks
+
+> [!IMPORTANT]
+> Before performing any commit, check if `pre-commit` is installed and configured with the expected hooks (`isort`, `pyink`, `addlicense`, `mdformat`). If not, remind the user to set up pre-commit hooks using the `adk-setup` skill.
