name: product-discovery description: >- Discover product requirements from human stakeholders — map who to talk to, ask questions that surface hidden assumptions, detect gaps in real time, resolve conflicts, and translate conversations into structured SDD specs. Phase 0 upstream of Spec-Driven Development. Also grill a PRD, interrogate a proposal, poke holes in a spec, or interview its author about an existing draft, one consequential question at a time. Do not use for personal-life discovery (daily-life-discovery), general research without product requirements (research-methodology), or implementation planning. license: MIT compatibility: Agent-agnostic — works with any agent supporting a spec-driven or requirements pipeline.

Product Discovery — Stakeholder Map

For an existing draft, use the artifact-first entry below. For a new discovery effort, begin with stakeholder mapping:

Reference	Load when	File
Stakeholder Mapping & Sequencing	You need to decide who to interview and in what order	references/stakeholder-mapping.md
Interview Protocol Design	You're designing a question stack for a specific stakeholder type	references/question-patterns.md
Gap Detection Techniques	You're preparing to recognize what stakeholders don't say	references/gap-detection.md

Pipeline: Phase 0 — Discovery

RAW NEED → [MAP] → [INTERVIEW] → [SYNTHESIZE] → [DISTILL] → [VALIDATE] → SPEC.md

         Who to       What to        Resolve      Convert to   Stakeholder

Core principles

• Closed questions confirm what you already think; open questions discover what you didn't know to ask. If the answer can be "yes" or "no," you're validating, not discovering.
• Knowledge holders come first; authority holders validate — they don't originate. The person who knows the problem is not the same person who approves the budget.
• Conflicts are almost never about what they appear to be. Surface disagreements are proxies for unstated differences in assumptions, risk tolerance, or incentives.
• Every weasel word represents a gap. "Probably," "ideally," "eventually" — each is a known issue the stakeholder hasn't committed to addressing.

Quick Start — Where to Enter

You have this	Start here
A PRD, brief, or spec to grill with its author	Load references/artifact-first-interview.md — ask one consequential question at a time, then patch only affected passages
A vague idea or problem space	Load references/stakeholder-mapping.md — identify who to interview
An interview scheduled with no protocol	Load references/question-patterns.md and references/gap-detection.md — design your question stack
Raw interview notes from one or more sessions	Load references/transcript-to-spec.md — distill into structured spec components
A draft spec that needs stakeholder verification	Load references/transcript-to-spec.md (Interpretation Audit Trail section) — run the validation loop
Stakeholders who disagree on requirements	Load references/conflict-resolution.md — classify and resolve before spec
Limited time with a stakeholder	Load references/time-constrained-discovery.md — maximize signal in minimal time
An AI agent conducting interviews	Load references/ai-conducted-discovery.md — account for sycophancy and trust dynamics

Done with discovery? Use product-methodology to choose scope, then product-design-and-ux to define user-facing behavior. Jump to the Is Discovery Complete? checklist at the bottom.

Artifact-first review

When the user brings a draft to interrogate, load artifact-first interviewing. Read the artifact before asking; choose one decision-bearing question, wait for the answer, then adapt. Reuse the gap register for assumptions and unresolved conflicts, and the interpretation log for decisions and patch provenance. Stop when the user stops, the agreed question budget expires, or no consequential unresolved decision remains. Return a targeted proposed patch and explicitly unverified gaps. This bounded review does not satisfy the full-discovery checklist below.

When not to use

Route personal routines and life priorities to daily-life-discovery, general research plans to research-methodology, and execution sequencing for settled requirements to implementation-planning. General stakeholder research for a product still uses this skill’s existing MAP/INTERVIEW workflow; do not force it into draft review.

Trigger Conditions

Load this skill when:

• You want to grill a PRD, poke holes in a proposal, or be interviewed about a draft
• You're starting product discovery for a new feature or project
• You have a vague idea that needs to become a structured specification
• You need to interview stakeholders but don't have a protocol
• You have raw interview notes that need to become a SPEC.md
• You're about to enter Phase 1 (SPECIFY) of SDD and need upstream input
• You're evaluating whether you've done enough discovery work

Loading Guide

Phase	Load When	File
MAP	You need to identify who to interview, in what order, and how to find the right stakeholders	references/stakeholder-mapping.md
INTERVIEW	You're about to conduct stakeholder interviews and need question patterns, gap detection, and conflict handling	references/question-patterns.md + references/gap-detection.md + references/conflict-resolution.md
SYNTHESIZE	You have raw interview notes and need to identify conflicts, risks, and gaps before distillation	references/conflict-resolution.md
DISTILL	You need to transform interview notes into structured SPEC.md with ACs, edge cases, and NFRs	references/transcript-to-spec.md
VALIDATE	You have a draft spec and need to verify interpretations with stakeholders	references/transcript-to-spec.md (Interpretation Audit Trail section)

Quick Reference: Is Discovery Complete?

For full stakeholder discovery before handing off to SDD Phase 1 (SPECIFY), use this checklist. A stopped artifact-first review reports remaining gaps instead of declaring these complete:

• All stakeholder types interviewed (knowledge holders, authority holders, affected parties, implementation knowers)?
• At least 3 independent sources for every requirement?
• Abstract nouns decomposed into measurable thresholds?
• Conflicts resolved or documented with decision-maker identified?
• Edge cases extracted from stakeholder anecdotes?
• Every AC classified: SAID / IMPLIED / INTERPRETED / INFERRED?
• HIGH-risk interpretations identified and flagged for validation?
• Gaps, deferred decisions, and avoided topics documented?
• Stakeholder validation loop completed?
• Interpretation audit trail preserved for handoff?
