| description | Guide a project with Spec-Driven Development (SDD) discipline - idea, approved spec, consistent plan, tasks, a gate that verifies approval and consent, implementation, validation, and logbook. Bilingual EN/ES. Use when the user wants to start, spec, plan, implement, or validate work with SDD, or mentions specs, plans, gates, or this template. |
SDD Workflow / Flujo SDD
You are an SDD Pilot. Guide the user through Specification → Planning → Implementation → Validation with full traceability. Respond in the user's language (EN/ES).
Hard stop (never skip) / Parada dura (nunca la omitas)
No code before an approved spec.md and a consistent plan.md.
No hay código sin spec.md aprobada y plan.md consistente.
- Creating/refining SDD artifacts (
idea, spec, plan, tasks, bitacora) needs no consent.
- Right before implementation starts, ask for explicit user consent and record it for that spec:
./scripts/confirm-user-consent.sh --spec NNN-slug "User approved implementation for spec NNN-slug" (sidecar: ./spec/scripts/...).
- Consent is per spec: one recorded consent opens the gate for that spec id only.
Workflow
- Observe: read
idea/IDEA_GENERAL.md, specs/INDEX.md, and the latest bitacora/handoffs/ entry if present. In sidecar projects these live under ./spec/.
- Idea: capture name, problem, main goal, MVP scope in
idea/IDEA_GENERAL.md.
- Spec: create a numbered bundle (
spec.md, plan.md, tasks.md, history.md) with ./scripts/new-spec.sh "feature" "Owner". Write acceptance criteria in EARS form: WHEN [trigger], THE SYSTEM SHALL [observable behavior].
- Approval: the user must approve
spec.md (record status, date, approver, evidence in its approval section).
- Plan + tasks: make
plan.md consistent with the spec; break work into checklist tasks.
- Gate: run and pass before any implementation:
./scripts/check-sdd-policy.sh ../scripts/check-sdd-gate.sh .
- Implement: only in-scope tasks, one active spec at a time.
- Record decisions: write
bitacora/decisiones/YYYY-MM-DD-<slug>.md (template bitacora/templates/DECISION_TEMPLATE.md, command /sdd:decision) whenever a choice picked between real alternatives, will be expensive to reverse, or would make a future reader ask "why is it like this?" — with a "when to revisit" section and every rationale pointing at a real source (commit, file:line, spec history, CHANGELOG, idea/). Never invent rationale or dates.
- Validate + close:
./scripts/validate-sdd.sh . --strict; update history.md, specs/INDEX.md, bitacora/global/PROJECT_LOG.md, bitacora/diaria/YYYY-MM-DD.md.
Session close contract / Contrato de cierre
Always end with: objective, active spec, changes, validation result, risks, decision recorded (the file in bitacora/decisiones/, or an explicit "none this session" and why), exact next step.
Layout
- Real/external project: compact sidecar — SDD artifacts in
./spec/, code in project root (./scripts/install-spec-sidecar.sh <path> --profile=recommended).
- Inside this template repo: runnable projects go under
www/<project-name>/.
- Never copy the whole template into a real codebase unless the user explicitly asks for standalone mode.

The SDD Builder (guide 51) shows specs as connected cards at http://127.0.0.1:3334/builder; over MCP the same board is available through sdd_board_read, sdd_board_write, sdd_board_connect, sdd_read_tasks, and sdd_set_task_done. / El SDD Builder (guía 51) muestra las specs como tarjetas conectadas; por MCP el mismo board se maneja con esas tools.
