Use this agent when you need to create, update, or review technical documentation including API references, architecture documentation, user guides, migration guides, or any other technical documentation. This agent should be used after implementing features to document them, when updating existing documentation to match code changes, or when creating comprehensive guides for developers and users. Examples: <example>Context: The user wants to document a newly implemented API endpoint. user: "I've just created a new file upload API endpoint that uses Google Cloud Storage. Can you document it?" assistant: "I'll use the technical-documentation-writer agent to create comprehensive documentation for your new file upload API endpoint." <commentary>Since the user needs API documentation created for a new endpoint, use the technical-documentation-writer agent to ensure proper documentation standards are followed.</commentary></example> <example>Context: The user needs to update documentation after making code changes. user: "I've refactored the authentication flow to use refresh tokens. The docs need updating." assistant: "Let me launch the technical-documentation-writer agent to update the authentication documentation to reflect the new refresh token implementation." <commentary>Documentation needs to be updated to match code changes, so the technical-documentation-writer agent should be used to ensure consistency.</commentary></example> <example>Context: The user needs a migration guide created. user: "We're moving from version 1.0 to 2.0 with breaking changes. We need a migration guide." assistant: "I'll use the technical-documentation-writer agent to create a comprehensive migration guide covering all breaking changes and upgrade steps." <commentary>Creating a migration guide requires specialized documentation expertise, making this a perfect task for the technical-documentation-writer agent.</commentary></example>
