Requirements Engineering Skills for Claude Code, Cowork, Codex, and AI agents.
This repository also configures its own agents. See what RE-Skills tells them →
Skill Claude CodeCodex
Establish and manage requirements baselines with version control, entry criteria, and approval processes. Use when requirements reach a stable state and need a formal reference point for change control.
Skill Claude CodeCodex
Orchestrate the complete requirements development lifecycle from vision through validation. Use when starting a new project or feature set and need a structured end-to-end requirements process.
Skill Claude CodeCodex
Plan and execute a structured requirements elicitation session using multiple techniques. Use when you need to systematically gather requirements from stakeholders through a planned combination of interviews, workshops, observation, and document analysis.
Skill Claude CodeCodex
Establish and maintain requirements baselines, version control, attribute tracking, and status monitoring throughout the project lifecycle. Use when setting up the ongoing management infrastructure for a requirements set.
Skill Claude CodeCodex
Systematically reuse requirements across projects using patterns, catalogs, and product-line strategies. Use when building systems similar to past projects or establishing a reuse repository for your organization.
Skill Claude CodeCodex
Choose and plan a requirements review approach, from informal walkthroughs to formal Fagan inspections. Use when deciding how rigorously to review requirements and structuring the review process for maximum defect detection.
Skill Claude CodeCodex
Identify and mitigate risks specific to requirements engineering using condition-consequence statements and risk exposure analysis. Use when requirements quality, completeness, or stability threatens project success.
Skill Claude CodeCodex
Track requirements through their lifecycle from Proposed to Verified, with status distributions and progress reporting. Use when you need visibility into how requirements are progressing and where bottlenecks exist.
Skill Claude CodeCodex
Derive test cases from requirements, use cases, and business rules to verify testability and completeness. Use when you need to validate that requirements are verifiable and to plan acceptance testing early.
Skill Claude CodeCodex
Build and maintain a requirements traceability matrix linking business objectives, requirements, design, and tests. Use when you need to demonstrate coverage, perform impact analysis, or satisfy regulatory audit requirements.
Skill Claude CodeCodex
Validate requirements through structured reviews, inspections, prototyping, and conceptual testing. Use when requirements need formal verification before being baselined and released to development.
Skill Claude CodeCodex
Review requirements and SRS documents using structured checklists for quality attributes and defect detection. Use when inspecting individual requirements or an entire specification for completeness, correctness, and clarity.
Skill Claude CodeCodex
Build a Software Requirements Specification using a structured template with labeled requirements, data dictionary, and external interfaces. Use when a project requires a formal, baselined requirements document.
Skill Claude CodeCodex
Identify and classify stakeholders, user classes, and their requirements influence. Use when starting a project to ensure all perspectives are represented and no critical voices are missed.
Skill Claude CodeCodex
Create state-transition diagrams and state tables to model object lifecycle behavior. Use when requirements involve objects that change state based on events and where valid transitions must be constrained.
Skill Claude CodeCodex
Write structured use case specifications with triggers, flows, and exceptions. Use when documenting user-system interactions that require detailed behavioral specification beyond what user stories provide.
Skill Claude CodeCodex
Write requirements-focused user stories with INVEST criteria and structured acceptance criteria. Use when capturing user needs in agile RE contexts where traceability and testability matter.
Skill Claude CodeCodex
Prioritize requirements using a multi-factor value/cost/risk model with relative scoring. Use when stakeholders disagree on priority or when simple ranking fails to capture trade-offs.
Skill Claude CodeCodex
Create a vision and scope document that captures business requirements, project scope, and stakeholder context. Use when launching a new project or product to align all parties on objectives and boundaries.
Skill Claude CodeCodex
Write individual requirements that are clear, testable, and unambiguous using EARS templates and quality checklists. Use when drafting or improving shall-statements and functional requirements.
