ADD

ADD (AI-Driven Development) — a minimal, state-tracked workflow: the AI writes the code, the human owns direction and verification. Drives every feature through one lean PLAN.md: Specify → Plan → Tests & Scenarios → Build → Verify → Observe, red/green TDD built in. Use whenever a repo has `.add/`, or the user says "add", "start a task", "next phase", "specify this feature", "ADD method", "AI-driven development", or wants spec/tests-first discipline over vague-prompt coding. Also resumes work across sessions via `.add/state.json` (never re-read the whole repo).

Author or improve an ADD-method persona file (a .add/personas/ slug.md) — the project-fit requirements LENS the ADD engine validates and the design/build/verify/advisor surfaces load. Use when adding a domain expert to the ADD roster, when the add-worker persona mode must DRAFT a persona because none fits the task kind, or when folding a retrospective into an existing persona. Produces a schema-valid persona (Identity, Critical Rules, Default Requirement, Success Metrics, plus recommended frontmatter and Abilities/Anti-patterns/Playbook) that carries the judgment layer of strong agent design: earned-perspective identity, bold-lead rules, the qualification gate, read-before-you-assert, failure-mode-aware metrics, defended budgets, and per-flow stances. Seeds a first draft from the teacher library or a sample subagent when a near-fit source exists, instead of a blank page.
