A user-research command that turns a product requirements document, or PRD, into an interview guide. A PRD describes what a product should solve and contain.

Use it to choose between exploratory and validation interviews and produce a complete guide with questions, moderator notes, and an internal briefing.

It identifies missing information in the PRD and helps avoid leading questions that encourage people to agree instead of describing real past behavior.

Per session 17 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 425 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00017	$0.00425
Opus 5	$0.00009	$0.00212
Sonnet 5	$0.00003	$0.00085
Haiku 4.5	$0.00002	$0.00042

Measured 11d ago against content hash 9fb6d20d9138, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

research 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 11d 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.

What it actually says

Paso 0 (obligatorio): Cargar ground-rules. Antes de proceder, lee shared-config.md y aplica:

§Filosofía del Plugin — modo copiloto, NO inventar, preguntar antes de generar

§Estilo de Escritura — frases ≤30 palabras, sin adjetivos sin datos, NUNCA inventar métricas

§Antipatrones Compartidos — los 7 antipatrones a detectar

Si no puedes leer el fichero, detén la ejecución y reporta el problema.

Ejecuta /research-from-prd completo: Gap Detection → Diseño de entrevistas.

Input necesario: Ruta de fichero, URL del documento, o contenido pegado del PRD.

Proceso:

Cargar PRD
Leer el SKILL.md de skills/research-from-prd/
Ejecutar Paso 0: Gap Detection (si no se ha ejecutado antes)
Determinar modo:
- Descubrir: Entrevistas exploratorias (problema poco explorado)
- Validar: Entrevistas de validación (hipótesis ya formuladas)
Leer references:
- prd-to-interview-mapping.md para mapeo PRD → preguntas
- mom-test-principles.md para reglas de entrevista
Generar guión completo de entrevista con 5 fases

Output: Guión de entrevista + briefing interno + notas para moderador.

Siguiente paso: Realizar entrevistas → /analyze-research con las notas.

Nota: Si vienes de /from-gsd y tienes phases/N/RESEARCH.md con evidencia previa, indícalo al comando con --evidence-from=.planning/phases/N/RESEARCH.md para no duplicar trabajo.

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.
