About this skill

SPARC Implementation Planning Skill

Purpose

Create comprehensive, structured implementation plans for significant development work using the SPARC (Specification, Pseudocode, Architecture, Refinement, Completion) framework.

SPARC Framework Overview

SPARC is a five-phase development methodology:

  1. Specification: Define requirements, constraints, and success criteria
  2. Pseudocode: Create high-level algorithm descriptions
  3. Architecture: Design system structure and component interactions
  4. Refinement: Iteratively improve and optimize
  5. Completion: Finalize, document, and verify

When to Load Additional References

The workflow below covers the essential SPARC planning process. Load detailed references when:

For detailed phase descriptions and templates:

Read `~/.claude/skills/sparc-planning/references/REFERENCE.md`

Use when: Need specification templates, pseudocode examples, architecture patterns, refinement checklists, completion criteria templates

For implementation templates:

Read `~/.claude/skills/sparc-planning/references/TEMPLATE.md`

Use when: Creating actual planning documents, need document structure, formatting guidelines

For test scenarios and examples:

Read `~/.claude/skills/sparc-planning/references/test-scenarios.md`

Use when: Planning test strategy, defining test cases, comprehensive testing examples

Workflow

Quick 12-Step SPARC Process

  1. Invoke check-history - Gather context about existing work
  2. Gather Requirements - Ask clarifying questions, document responses
  3. Research Dependencies - Use Context7 for library documentation if needed
  4. Create Phase 1 - Specification - Functional/non-functional requirements, constraints, success criteria
  5. Create Phase 2 - Pseudocode - Algorithm pseudocode, component interfaces
  6. Create Phase 3 - Architecture - Components, patterns, data models, interactions, security/performance architecture
  7. Create Phase 4 - Refinement Plan - Code quality, optimization, security review, test coverage
  8. Create Phase 5 - Completion Criteria - Completion checklist, documentation requirements, deployment plan
  9. Generate Ranked Task List - Break down into ordered, estimated tasks with owners
  10. Identify Dependencies and Blockers - Create dependency graph, identify risks and mitigations
  11. Create Security & Performance Plans - Security checkpoints, performance targets and measurement
  12. Document and Present Plan - Save all planning docs, present summary to user

For detailed step-by-step workflow with templates, examples, and code samples, see references/WORKFLOW-STEPS.md.

Integration with Other Skills

This skill invokes:

  • check-history - Step 1 (gather context)

This skill may be followed by:

  • manage-branch - Create feature branch
  • safe-commit - Commit planning documents

Best Practices

  1. Be thorough - Better to over-plan than under-plan
  2. Be specific - Vague plans lead to vague implementations
  3. Consider all aspects - Security, performance, testing, documentation
  4. Identify risks early - Mitigation is easier with planning
  5. Make it reviewable - User should be able to understand and validate plan
  6. Save everything - Plans are valuable documentation
  7. Be realistic - Estimate time conservatively

When to Skip Planning

Some tasks don't need full SPARC planning:

  • Simple bug fixes - Go straight to implementation
  • Documentation updates - No architecture needed
  • Trivial refactoring - Single file, obvious change
  • Configuration changes - Low risk, reversible

Rule of thumb: If implementation is < 4 hours and touches < 3 files, skip formal planning.

Adapting SPARC for Different Project Sizes

Small feature (< 8 hours)

  • Brief specification (1 paragraph)
  • Simplified pseudocode
  • Component list (no diagrams)
  • Basic task list
  • Standard checklist

Medium feature (8-40 hours)

  • Detailed specification
  • Comprehensive pseudocode
  • Architecture diagrams
  • Detailed task list with estimates
  • Security & performance plans

Large feature (> 40 hours)

  • Full SPARC documentation
  • Multiple architecture views
  • Dependency graphs
  • Risk assessment matrix
  • Milestone planning

Troubleshooting

Common Planning Problems:

  • Requirements incomplete or vague → Break down, focus on MVP
  • Too many dependencies/blockers → Re-scope, identify alternatives
  • Estimated time unrealistic → Use time-boxing, add research spikes
  • Architecture reveals fundamental issues → STOP, revise requirements
  • Plan too detailed/taking too long → Simplify, time-box to 90 minutes
  • Plan doesn't match team conventions → Review check-history, align patterns
  • User rejects plan → Iterate, clarify gaps, revise and re-present

For detailed troubleshooting with symptoms, solutions, and examples, see references/TROUBLESHOOTING.md.

Quick Reference

Invoke SPARC planning when:

  • User requests implementation plan
  • Starting significant feature (> 8 hours)
  • Making breaking changes
  • Refactoring multiple components
  • Need architecture decision record

Output artifacts:

  1. Specification document
  2. Pseudocode for algorithms
  3. Architecture design
  4. Refinement plan
  5. Completion checklist
  6. Ranked task list
  7. Security plan
  8. Performance plan

Next step after planning: Review with user, get approval, create branch, begin implementation.
