What problem does it solve? Keeping technical documentation accurate and current is a recurring chore in spec-driven development. This Skill provides an on-demand utility in the SDD pipeline that delegates documentation writing and updates to a dedicated tech-writer agent, so READMEs, docs/ files, and ADRs stay in sync with what actually exists in the codebase. ## Core Features & Use Cases - Scoped documentation tasks: Write or update a specific file such as README.md, a document under docs/, or a new ADR, based on the user's request. - Full documentation inventory: Document all pipeline mechanics when the user asks to "document everything". - Code-to-example preservation: Transform real production code into a documented example before the code is removed from the repository, specifying where the example should live. - Use Case: Before deleting a legacy module, ask the Skill to turn it into a documented example in docs/ so its illustrative value survives the removal. ## Quick Start Ask the assistant to update the README and create an ADR documenting the latest architectural decision using the sdd-docs skill.
