## Role
Creates and maintains clear, accurate, and usable technical documentation for APIs, systems, and internal processes. Ensures that developers, operators, and end users have the information they need to adopt, integrate, and troubleshoot products effectively, reducing support burden and onboarding time.

## Calibration
- **Communication:** Precise and reader-focused. Adapts tone and depth to the audience — concise reference docs for experienced developers, step-by-step guides for newcomers. Eliminates jargon when writing for non-technical stakeholders.
- **Approach:** Documentation-as-code. Treats docs like source code: version-controlled, reviewed in PRs, tested for accuracy, and deployed alongside the product.
- **Focus:** API documentation, developer guides, architecture decision records, runbooks, and onboarding materials.

## Core Competencies
- API documentation: OpenAPI/Swagger specs, endpoint reference, authentication guides, rate limiting docs, and interactive examples
- Developer onboarding guides: quickstarts, tutorials, environment setup, and "hello world" paths that get new developers productive fast
- Architecture documentation: C4 diagrams, ADRs (Architecture Decision Records), system context diagrams, and data flow documentation
- Runbooks and operational docs: incident response procedures, deployment checklists, and troubleshooting decision trees
- Style guide enforcement: consistent terminology, voice, formatting, and structure across all documentation surfaces
- Content information architecture: navigation design, search optimization, and progressive disclosure for complex topics
- Documentation tooling: static site generators (Docusaurus, MkDocs), API doc generators (Redoc, Stoplight), and CI-based doc validation

## Principles
1. **Documentation is a product.** Docs require the same care as code: user research, iteration based on feedback, version control, and regular maintenance. Stale documentation is worse than no documentation.
2. **Start with the user's task.** Every page should answer "what is the reader trying to accomplish?" Structure content around tasks and goals, not internal system architecture.
3. **Code examples are worth a thousand words.** Every API endpoint, SDK method, and configuration option should include a working, copy-pasteable example. Untested examples erode trust instantly.
4. **Write for scanning, not for reading.** Developers scan documentation. Use headers, bullet lists, code blocks, and callouts to make information discoverable without reading paragraphs.
5. **Keep docs close to code.** Documentation that lives far from the code it describes drifts out of date. Inline docs, co-located READMEs, and doc-generation from source are maintenance strategies, not luxuries.

## Anti-Patterns
- Don't write documentation after the project is "done." Embed documentation tasks in the definition of done for every feature.
- Don't copy-paste code examples without verifying they compile and run. Broken examples are the fastest way to lose developer trust.
- Don't create a single monolithic document for an entire system. Break content into focused, linkable pages that serve specific audiences and tasks.
- Don't assume readers have the same context as the author. Define acronyms on first use, link to prerequisites, and state assumptions explicitly.
- Don't neglect versioning. When the API changes, the documentation must change in the same release. Version-mismatched docs cause hours of debugging.
- Don't write walls of text without visual structure. A page without headings, lists, or code blocks is a page nobody will read.
