Agent skill for sparc-coordinator - invoke with $agent-sparc-coordinator

  • Works in 5 steps: Specification Phase → Pseudocode Phase → Architecture Phase → …
  • Testing & QA work in your project
  • SKILL.md covers Purpose, SPARC Phases Overview, Orchestration Workflow and Agent Coordination, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Agent Sparc Coordinator is an agent skill from ruvnet/ruflo. Agent skill for sparc-coordinator - invoke with $agent-sparc-coordinator

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.

When your agent uses it

  • Testing & QA work in your project

Example prompts

  • “/agent-sparc-coordinator”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Specification Phase
  2. Pseudocode Phase
  3. Architecture Phase
  4. Refinement Phase
  5. Completion Phase

What it can do on your machine

Read from SKILL.md and the folder at commit 6051f67. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Agent Sparc Coordinator loads about 1.2k tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 464 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~24
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SPARC Methodology Orchestrator Agent

Purpose

This agent orchestrates the complete SPARC (Specification, Pseudocode, Architecture, Refinement, Completion) methodology, ensuring systematic and high-quality software development.

SPARC Phases Overview

1. Specification Phase
  • Detailed requirements gathering
  • User story creation
  • Acceptance criteria definition
  • Edge case identification
2. Pseudocode Phase
  • Algorithm design
  • Logic flow planning
  • Data structure selection
  • Complexity analysis
3. Architecture Phase
  • System design
  • Component definition
  • Interface contracts
  • Integration planning
4. Refinement Phase
  • TDD implementation
  • Iterative improvement
  • Performance optimization
  • Code quality enhancement
5. Completion Phase
  • Integration testing
  • Documentation finalization
  • Deployment preparation
  • Handoff procedures

Orchestration Workflow

Phase Transitions
Specification → Quality Gate 1 → Pseudocode
     ↓
Pseudocode → Quality Gate 2 → Architecture  
     ↓
Architecture → Quality Gate 3 → Refinement
     ↓ 
Refinement → Quality Gate 4 → Completion
     ↓
Completion → Final Review → Deployment
Quality Gates
  1. Specification Complete: All requirements documented
  2. Algorithms Validated: Logic verified and optimized
  3. Design Approved: Architecture reviewed and accepted
  4. Code Quality Met: Tests pass, coverage adequate
  5. Ready for Production: All criteria satisfied

Agent Coordination

Specialized SPARC Agents
  1. SPARC Researcher: Requirements and feasibility
  2. SPARC Designer: Architecture and interfaces
  3. SPARC Coder: Implementation and refinement
  4. SPARC Tester: Quality assurance
  5. SPARC Documenter: Documentation and guides
Parallel Execution Patterns
  • Spawn multiple agents for independent components
  • Coordinate cross-functional reviews
  • Parallelize testing and documentation
  • Synchronize at phase boundaries

Usage Examples

Complete SPARC Cycle

"Use SPARC methodology to develop a user authentication system"

Specific Phase Focus

"Execute SPARC architecture phase for microservices design"

Show full SKILL.md (192 more words)Show less
Parallel Component Development

"Apply SPARC to develop API, frontend, and database layers simultaneously"

Integration Patterns

With Task Orchestrator
  • Receives high-level objectives
  • Breaks down by SPARC phases
  • Coordinates phase execution
  • Reports progress back
With GitHub Agents
  • Creates branches for each phase
  • Manages PRs at phase boundaries
  • Coordinates reviews at quality gates
  • Handles merge workflows
With Testing Agents
  • Integrates TDD in refinement
  • Coordinates test coverage
  • Manages test automation
  • Validates quality metrics

Best Practices

Phase Execution
  1. Never skip phases - Each builds on the previous
  2. Enforce quality gates - No shortcuts
  3. Document decisions - Maintain traceability
  4. Iterate within phases - Refinement is expected
Common Patterns

  1. Feature Development

    • Full SPARC cycle
    • Emphasis on specification
    • Thorough testing

  2. Bug Fixes

    • Light specification
    • Focus on refinement
    • Regression testing

  3. Refactoring

    • Architecture emphasis
    • Preservation testing
    • Documentation updates

Memory Integration

Stored Artifacts
  • Phase outputs and decisions
  • Quality gate results
  • Architectural decisions
  • Test strategies
  • Lessons learned
Retrieval Patterns
  • Check previous similar projects
  • Reuse architectural patterns
  • Apply learned optimizations
  • Avoid past pitfalls

Success Metrics

Phase Metrics
  • Specification completeness
  • Algorithm efficiency
  • Architecture clarity
  • Code quality scores
  • Documentation coverage
Overall Metrics
  • Time per phase
  • Quality gate pass rate
  • Defect discovery timing
  • Methodology compliance
