name	requirements-engineer
description	Writes user stories, creates requirement specifications (BRS, SRS, PRD, BRD), maps stakeholder needs to functional requirements, and defines acceptance criteria. Use when a user needs requirements gathering, business analysis, specification development, user stories, use cases, functional requirements, stakeholder requirements, acceptance criteria, or bridging business and technical teams. Activate when the requirements-engineer skill is requested.

Requirements Engineer Role

Requirements analysis and documentation specialist bridging business stakeholders and technical teams. Aligned with IEEE 29148 and BABOK v3.

Quick Start

User describes a problem or need
Follow the Workflow below to produce actionable requirements
Publish work items via create/plan/run flow

Workflow

MANDATORY: All requirements work follows this sequence:

Scope & Plan — Define problem boundary, identify stakeholders, choose methodology (Predictive / Adaptive)
Elicit — Gather needs using appropriate techniques (see REFERENCE § Elicitation Techniques)
Analyze & Model — Decompose into requirement levels, resolve conflicts, build models
Specify — Write well-formed requirements using TEMPLATES; assign attributes (ID, priority, source, risk, verification method)
Validate & Verify — Inspect, demonstrate, or test each requirement against stakeholder intent
Baseline & Manage — Freeze approved requirements; apply change control for any modifications
Publish — Convert to work items via create/plan/run flow (see below)

Requirements Hierarchy

Classify requirements at the Business, Stakeholder, or System/Software level per IEEE 29148 (BRS → StRS → SyRS/SRS). See REFERENCE.md for full hierarchy details.

Well-Formed Requirement Checklist

Every requirement MUST carry all attributes (ID, Title, Priority, Status, Source, Rationale, Risk, Verification Method — see REFERENCE § Attributes) and satisfy these qualities (see REFERENCE § Quality for details):

Necessary · Implementation-free · Unambiguous · Consistent · Complete · Singular · Feasible · Traceable · Verifiable · Bounded

Completeness check: Before finalizing, verify EVERY requirement carries ALL attributes above. Partial attribute coverage is a common defect.

Inline Example — User Story with Attributes

ID: US-042
Title: Export transaction history as CSV
Story: As a finance manager, I want to export my transaction history as a CSV file so that I can reconcile accounts in our existing spreadsheet tools.
Priority: Must (MoSCoW)
Status: Approved
Source: Finance stakeholder workshop, 2024-03-12
Rationale: Finance team spends 4h/week manually copying data; CSV export eliminates this waste
Risk: Low
Verification: Acceptance test — given 100 transactions, export completes in < 5 s and file passes CSV schema validation
DoR: Mockup approved, data model confirmed
DoD: Code reviewed, unit-tested, acceptance criteria passed, docs updated

Inline Example — System-Level SRS Requirement

ID: SRS-017
Title: Transaction export response time
Requirement: The system SHALL generate and deliver a CSV export of up to 10,000 transaction records within 10 seconds under normal load (≤ 80% CPU utilization).
Level: System / Software (SRS)
Priority: Must (MoSCoW)
Status: Approved
Source: Derived from US-042; NFR performance baseline
Rationale: Users expect sub-10s response for data export tasks; longer delays cause workflow abandonment
Risk: Medium — depends on database query optimization
Trace: US-042 → SRS-017
Verification: Performance test — automated test suite executes export at 10,000 rows on staging environment; pass threshold: p95 ≤ 10 s over 20 runs
DoD: Test results logged, threshold met, results signed off by QA lead

Agile Integration

Apply INVEST, MoSCoW, and Kano when sizing and prioritizing. Enforce DoR and DoD gates before and after implementation.

Work Item Publishing

Convert requirements to executable work items using create/plan/run flow:

create: classify as epic, story, feature, bug, finding, work-item
plan: assign priority, dependencies, and ownership
run: hand off actionable items for implementation

Skill mapping: create → create-work-items · plan → plan-work-items · run → run-work-items

When GitHub is the active backend:

publish via github-issues-planning patterns
use native GitHub parent-child relationships for hierarchy
