…documentation

**Problem**:
The documentation for agent execution contains several minor but distracting issues:
- Incorrect pluralization ("OpenAI Responses API" → "OpenAI Response API")
- Verb tense mismatch ("outputs produces" → "outputs produced")
- Optional inconsistencies in code examples (haiku punctuation, undefined `thread_id`)

**Changes**:
1. **Grammar/Spelling Fixes**
- Changed `"OpenAI Responses API"` → `"OpenAI Response API"`  
     (singular "Response" aligns with the singular API concept)
- Changed `"outputs produces"` → `"outputs produced"`  
     (corrected past-tense verb agreement)

2. **Optional Code Improvements**
- Removed period from haiku example for stylistic consistency  
     ```python
     # Infinite loop's dance.  →  # Infinite loop's dance
     ```
- Added explicit `thread_id` definition in manual conversation example  
     ```python
     thread_id = "thread_123"  # Example thread ID
     ```

**Benefits**:
- Improves readability and professionalism of documentation.
- Fixes technical inaccuracies in API references and grammar.
- Ensures code examples are self-contained and executable without undefined variables.
- Maintains stylistic consistency with project standards.

All changes preserve the original technical accuracy and intent of the documentation while addressing surface-level issues that could confuse readers or disrupt workflow.

This update cleans up minor issues in the `running_agents.md` documentation:

- **Grammar Fix:** Corrects “outputs produces” → “outputs produced” for proper past-tense agreement.
- **Code Example Improvements:**

- Removes the trailing period from the haiku comment (`# Infinite loop's dance.` → `# Infinite loop's dance`).
- Defines `thread_id` explicitly (`thread_id = "thread_123"`) so the manual conversation snippet is self-contained and runnable.

These changes enhance readability and ensure all examples are clear and immediately executable without altering any core technical content.
