Tools

• vdd_amend ~352 tokens
  VDD Cross-phase: Plan a requirement-change cascade through the whole chain — identifies the highest affected level and returns the ordered steps to update downward V→S→T→SP→PL→TK and re-run affected gates (G1–G7). Read-only; returns the cascade plan without editing artifacts (the host agent applies
• vdd_clarify ~472 tokens
  VDD Phase 4b: Clarify an existing spec — scans vdd/specs/<feature>/spec.md and returns the items to resolve: every [NEEDS CLARIFICATION] marker, [e.g.] placeholder, and happy-path acceptance criterion (AC) still needing an edge-case counterpart (AC-E*). Read-only; returns the list without editing th
• vdd_clone ~666 tokens
  Crawl and capture a target domain into a clone dataset + manifest — WordPress-aware schema inference, Payload collections, and a Next.js + Payload + Postgres scaffold manifest (vdd/clone-manifest.json). Pass the domain as description. Writes vdd/clone-dataset.json, vdd/clone-manifest.json, and vdd/c
• vdd_detect_environment ~422 tokens
  VDD Environment Detection: Report which tools/MCPs each VDD phase requires vs treats as optional — across the 8-phase pipeline (init through validate) plus the cross-phase helpers (amend, clone, inspect, get-next-task) — and which of the host agent availableTools are present vs missing. Read-only; r
• vdd_get_next_task ~444 tokens
  VDD Phase 7a: Read vdd/specs/<feature>/tasks.md and return the next uncompleted task (or a completion marker when none remain). Read-only; never edits tasks.md. Pass feature (the exact spec directory name). Use before each implementation session to keep context isolated; to regenerate the whole list
• vdd_implement ~481 tokens
  VDD Phase 7b: Prepare one task for implementation — loads constitution, spec, plan, and contracts and returns the implementation instruction plus the impact-chain commit-message format. Read-only; the tool writes nothing — the host agent performs the code edits, verification, and commit. Pass taskId
• vdd_init ~276 tokens
  VDD Phase 0: Generate constitution.md at the project root — the immutable tech stack, conventions, security constraints, naming rules, and banned patterns that every later phase obeys. Overwrites any existing constitution.md. Run this first, before vdd_vision; to change a constitution that already e
• vdd_inspect Changes files · ~572 tokens
  VDD Cross-phase: Read-only inspection of the current project in one call — scope selects the view. scope="project" (default) returns the bidirectional V→S→T→SP→PL→TK traceability matrix across all vdd/ artifacts; scope="feature" returns per-feature spec metrics (acceptance-criteria count, unresolved
• vdd_plan ~314 tokens
  VDD Phase 5: Generate the technical blueprint under vdd/specs/<feature>/ — plan.md (component breakdown, AC coverage map, technology choices, verification toolchain), data-model.md (entities, indexes, migrations), and contracts/ (request/response/error schemas). Overwrites these files. Requires an e
• vdd_specify ~425 tokens
  VDD Phase 4: Generate vdd/specs/<id>/spec.md for one tactical action item — user stories, Always/Ask/Never boundaries, Given/When/Then acceptance criteria (AC), MoSCoW priorities, non-functional requirements, and impact verification. Overwrites the spec file. Pass actionItemId (e.g. "A-001") or a fr
• vdd_strategize ~437 tokens
  VDD Phase 2: Produce research-backed strategy into vdd/strategy.md — strategic pillars, competitive analysis, and a risk register, resolved from the vision target-domain primers. Overwrites vdd/strategy.md. Requires vdd/vision.md; run after vdd_vision and before vdd_tactics. Two-pass: call once with
• vdd_tactics ~481 tokens
  VDD Phase 3: Audit the existing codebase into vdd/tactics.md — repo audit, technical-debt assessment, gap analysis, MoSCoW-prioritized action items (A-001, A-002, …), dependency map, and infrastructure requirements. Overwrites vdd/tactics.md. Requires vdd/strategy.md; run after vdd_strategize and be
• vdd_tasks ~291 tokens
  VDD Phase 6: Break the plan into atomic test-first tasks in vdd/specs/<feature>/tasks.md — each references acceptance criteria (AC) and contracts, is sized S/M/L, and is marked [P] when parallelizable. Overwrites tasks.md. Requires plan.md; run after vdd_plan. To fetch the next uncompleted task from
• vdd_validate ~458 tokens
  VDD Phase 8: Validate the full chain — bidirectional traceability matrix, drift detection, orphan detection, uncovered vision goals, impact metrics vs targets, and 28 S&T assumption checks across 7 gates. Writes vdd/impact-report.generated.md and never overwrites a hand-authored vdd/impact-report.md
• vdd_vision ~315 tokens
  VDD Phase 1: Expand a freeform vision statement into vdd/vision.md — Impact Model (Goal, Actors, Impacts), Stakeholder Map, Success Metrics (leading + lagging), Constraints & Boundaries, and Target Domains. Overwrites any existing vdd/vision.md. Requires statement (freeform 1-3 paragraph intent, not
