I've reviewed the changes in this PR which focuses on fixing sample agents prompts. Here's my feedback:

1. Changes in github-docs-agent/main.py:

   • Good fix: Adding the f prefix to the string literal to properly support string formatting
   • This is a necessary correction as the system message might need to use formatted strings later

2. Changes in github-reviewer-agent/main.py:

   • Good improvement: Breaking down the long string into multiple lines for better readability
   • Added clarification about posting the review in PR comments which makes the agent's task clearer

3. Version Updates:

   • github-docs-agent: 0.0.2 → 0.0.3
   • github-reviewer-agent: 0.0.3 → 0.0.4
   • Appropriate version bumps for these changes

Overall, these changes are straightforward and improve the functionality and clarity of the agent prompts. The code changes are well-structured and maintain good Python practices. The versioning updates are appropriate for the scope of changes.

The changes look good and are ready to be merged. 👍
