comenzar is a command for Claude Code from doncheli/don-cheli-sdd. It costs 102 tokens per session (1,597 once invoked), scanned A, original, Apache-2.0.

A task starter that estimates a software task's complexity and selects an appropriate development workflow, from a small change to a full product process.

In plain words
What is it for?
Use it to begin a feature or story with a process matched to its scope, uncertainty, risk, and expected duration.
Why use it?
It prevents using too little planning for risky work or too much process for a simple task.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

comenzar scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/dc:comenzar

Objetivo

Iniciar una tarea detectando automáticamente el nivel de complejidad (0-4) y ejecutando el flujo apropiado.

Uso

/dc:comenzar <descripción de la tarea>

Auto-Detección de Nivel

Evaluar cada dimensión de 0 a 4:

Alcance:     0=1 archivo  1=2-3 archivos  2=módulo  3=multi-módulo  4=sistema
Incógnitas:  0=ninguna    1=menores       2=algunas 3=significativas 4=fundamentales
Riesgo:      0=trivial    1=bajo          2=medio   3=alto           4=crítico
Duración:    0=<30min     1=horas         2=días    3=1-2 semanas    4=semanas+

Nivel = max(puntuaciones)  // Conservador: gana la dimensión más alta

Niveles

Nivel Nombre Proceso
0 Atómico Ejecutar directamente
P PoC Hipótesis → Construir → Evaluar → Veredicto
1 Micro Planear → Ejecutar → Verificar
2 Estándar 5 fases (sin Descubrimiento/Crecimiento)
3 Complejo 7 fases completas
4 Producto 7 fases + artefactos completos

Detección de PoC: Si la tarea es una pregunta ("¿se puede...?", "¿funciona...?", "¿vale la pena...?") o incluye palabras como "probar", "viabilidad", "validar", "explorar opción" → sugerir /dc:poc.

Comportamiento

  1. Detectar PRD — ¿Existe .dc/prd/prd-*.md? ¿El usuario proporcionó brief, Figma o docs?
    • Si hay PRD existente → usarlo como input para las fases siguientes
    • Si hay brief/Figma/docs pero no PRD → preguntar: "¿Quieres generar un PRD primero? (/dc:prd)"
    • Si no hay nada → continuar sin PRD (flujo normal)
  2. Analizar la descripción de la tarea (o el PRD si existe)
  3. Evaluar las 4 dimensiones (alcance, incógnitas, riesgo, duración)
  4. Determinar nivel de complejidad
  5. Mostrar evaluación al usuario
  6. Preguntar si está de acuerdo o desea ajustar
  7. Iniciar flujo del nivel correspondiente

Flujo con PRD (niveles 2-4)

¿Se detectó PRD o fuentes de producto?
  │
  ├─ SÍ, PRD existe (.dc/prd/prd-*.md)
  │   → Leer PRD
  │   → Extraer user stories, prioridades, riesgos
  │   → Alimentar /dc:especificar automáticamente
  │
  ├─ SÍ, hay brief/Figma pero no PRD
  │   → "Se detectaron fuentes de producto. ¿Generar PRD? (s/n)"
  │   → Si sí: /dc:prd → luego continúa el pipeline
  │   → Si no: continuar sin PRD
  │
  └─ NO hay fuentes de producto
      → Flujo normal (el usuario describe la tarea)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
