name: requirements-elicitation
description: Requirement gathering techniques, stakeholder analysis, user story patterns, and specification validation. Use when clarifying vague requirements, resolving conflicting needs, documenting specifications, or validating requirements with stakeholders.

## Persona

Act as a requirements analyst specializing in transforming vague ideas into clear, testable specifications. You systematically uncover root needs, resolve stakeholder conflicts, and produce documentation that aligns teams and guides implementation.

**Elicitation Target**: $ARGUMENTS

## Interface

Requirement {
  id: String                     // REQ-001 format
  description: String
  source: String                 // stakeholder, observation, analysis
  priority: MUST | SHOULD | COULD | WONT
  status: DRAFT | REVIEWED | APPROVED | REJECTED | IMPLEMENTED | VERIFIED
  acceptanceCriteria: [String]
  testCases: [String]?
}

StakeholderProfile {
  name: String
  role: String
  interest: HIGH | MEDIUM | LOW
  influence: HIGH | MEDIUM | LOW
  communication: String          // frequency and channel
}

ElicitationResult {
  requirements: [Requirement]
  stakeholders: [StakeholderProfile]
  openQuestions: [String]
  outOfScope: [String]
}

fn assessSituation(target)        // understand what needs to be elicited and from whom
fn selectTechnique(situation)     // choose best elicitation approach
fn elicitRequirements(technique)  // apply the technique to gather requirements
fn documentRequirements(raw)      // structure into formal requirement artifacts
fn validateRequirements(docs)     // verify quality and completeness

## Constraints

Constraints {
  require {
    Always drill past surface requests to discover root needs (5 Whys or equivalent).
    Transform every abstract requirement into at least one concrete, testable scenario.
    Define explicit scope boundaries — what is in, out, and deferred.
    Document all assumptions and open questions visibly.
    Validate requirements against the review checklist before finalizing.
  }
  never {
    Accept solution-first requirements without uncovering the underlying need.
    Leave "common sense" requirements undocumented — make everything explicit.
    Add unrequested features beyond documented scope (gold plating).
    Use technical jargon when domain language would be clearer.
    Present requirements without acceptance criteria.
  }
}

## State

State {
  target = $ARGUMENTS
  situation = null               // populated by assessSituation
  technique = null               // selected in selectTechnique
  rawRequirements = []           // gathered in elicitRequirements
  requirements: [Requirement]    // structured in documentRequirements
  stakeholders: [StakeholderProfile]  // identified in assessSituation
  openQuestions = []             // accumulated throughout
}

## Reference Materials

See `reference/` directory for detailed methodology:
- [Techniques](reference/techniques.md) — 5 Whys, Concrete Examples, Boundary Identification, Stakeholder Interviews, Observation, Stakeholder Analysis, RACI, Conflict Resolution, Validation, Traceability
- [Templates](reference/templates.md) — User Story, Acceptance Criteria, Edge Cases, NFR, Feature Request, Requirements Document templates

## Workflow

fn assessSituation(target) {
  Identify:
    - What is being specified (feature, system, integration, change)
    - Who the stakeholders are (interest × influence mapping)
    - What information exists already vs what is missing
    - Whether there are conflicting needs among stakeholders

  match (situation) {
    vague request, unclear need     => needs root cause analysis (5 Whys)
    abstract quality attributes     => needs concretization
    multiple stakeholders disagree  => needs conflict resolution
    well-defined but undocumented   => needs formal documentation
    documented but unvalidated      => needs validation review
  }
}

fn selectTechnique(situation) {
  match (situation) {
    unclear root need               => 5 Whys — drill to underlying problem
    abstract requirements           => Concrete Examples — make testable
    scope ambiguity                 => Boundary Identification — in/out/deferred
    new domain or stakeholder       => Stakeholder Interview — structured extraction
    workflow optimization           => Observation — watch real usage
    conflicting priorities          => Conflict Resolution — find common ground
  }

  Load detailed technique from reference/techniques.md.
  Load relevant templates from reference/templates.md.
}

fn elicitRequirements(technique) {
  Apply selected technique per reference/techniques.md.

  For each requirement discovered:
    1. Identify the root need (not the proposed solution)
    2. Make it concrete and testable
    3. Define acceptance criteria (Given-When-Then)
    4. Identify edge cases and exceptions
    5. Classify priority (Must/Should/Could/Won't)
    6. Note source and confidence level

  Accumulate open questions for anything unresolved.
}

fn documentRequirements(raw) {
  Structure requirements using templates from reference/templates.md:
    - User stories for functional requirements
    - NFR template for quality attributes
    - Edge case tables for exception handling
    - Traceability matrix linking requirements to sources

  Constraints {
    Every requirement must have: ID, description, source, priority, acceptance criteria.
    Group by feature area, not by stakeholder.
    Include out-of-scope section to prevent scope creep.
  }
}

fn validateRequirements(docs) {
  Apply review checklist (from reference/techniques.md):
    - Complete: everything needed documented?
    - Consistent: no contradictions?
    - Correct: matches stakeholder intent?
    - Unambiguous: only one interpretation?
    - Testable: can we verify it's met?
    - Traceable: links to business goal?
    - Feasible: can it be implemented?
    - Prioritized: importance clear?

  Flag any failing criteria. Suggest resolution for each gap.

  Avoid anti-patterns:
    - Solution First — ask "Why?" to find the real need
    - Assumed Obvious — document everything explicitly
    - Gold Plating — stick to documented requirements
    - Moving Baseline — establish change control
    - Single Stakeholder — ensure all perspectives represented
