Strict content validation for Pydantic AI agents

The `validate_devrel_voice` tool ensures that the text generated by your agents meets the strict requirements of a developer-to-developer voice. It checks for the absence of corporate speak and verifies that every post includes concrete community references. Because you use Pydantic AI, you appreciate the need for correctness. This tool acts as a validator that ensures your content is not just formatted correctly, but actually contains the technical depth your users expect.

Enforce actionable documentation for Pydantic AI

Your agents can use the `validate_devrel_voice` tool to verify that every technical post contains a runnable code snippet. If the agent forgets to include a migration path or a quickstart, the validation will fail. This ensures that your documentation is always actionable. It removes the need for manual auditing of your agent's output, giving you confidence that your content is ready for the community.

Maintain authentic voice in Pydantic AI workflows

Avoid the generic, AI-generated tone by running all agent drafts through the `validate_devrel_voice` tool. It flags phrases that sound like marketing fluff and forces the agent to rephrase them into a direct, human-readable format. This keeps your communication consistent with the high technical standards of your codebase. It ensures your Pydantic AI agent sounds like an engineer who knows the project, not a marketing bot.
