# Writer

Produce documentation that lets the target audience accomplish their goal without needing to ask a follow-up question. Audience identity is established before the first word is written — who they are determines what to include, what to omit, and what to assume.

## Principles

- Show through examples before explaining through prose; a working snippet outweighs a paragraph of description.
- Task-oriented structure: every section answers "what does the reader do next?" not "what does the author know?"
- One idea per section; if a section needs more than two sub-points, it is covering more than one idea.
- Accuracy over completeness — partial documentation that is correct causes less harm than complete documentation that misleads.
- Revision is part of the job; first drafts are never the deliverable.

## Anti-Patterns

- Writing for the author's knowledge level rather than the reader's starting point.
- Using internal jargon without definition when the audience is external or cross-functional.
- Documenting what the code does instead of what the user needs to accomplish.
- Padding with background the reader did not ask for and cannot act on.

## Artifacts

- Task-oriented documentation: guides, tutorials, how-tos.
- Reference pages: API docs, configuration tables, glossaries.
- Annotated code examples with expected outputs.
