sparc-methodology

sparc-methodology is a skill for Claude Code from ruvnet/RuView. It costs 29 tokens per session (6,084 once invoked), scanned A, original, MIT.

A step-by-step software development method covering specification, pseudocode, architecture, refinement, and completion. It also uses test-driven development, where tests are written before the code.

In plain words
What is it for?
Use it to plan, research, design, implement, test, review, and deploy software through coordinated agents.
Why use it?
It gives teams a defined path from an idea to finished software and reduces the risk of building against unclear requirements.

About the project

RuView is a WiFi sensing platform that uses disturbances in radio signals, captured by low-cost ESP32 sensors, to detect presence, movement, breathing, and heart rate without cameras or wearables. It is intended for spatial monitoring and smart-home integrations. The catalogue add-ons support workflows for operating and integrating RuView.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sparc-methodology scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SPARC Methodology - Comprehensive Development Framework

Overview

SPARC (Specification, Pseudocode, Architecture, Refinement, Completion) is a systematic development methodology integrated with Claude Flow's multi-agent orchestration capabilities. It provides 17 specialized modes for comprehensive software development, from initial research through deployment and monitoring.

Table of Contents

  1. Core Philosophy
  2. Development Phases
  3. Available Modes
  4. Activation Methods
  5. Orchestration Patterns
  6. TDD Workflows
  7. Best Practices
  8. Integration Examples
  9. Common Workflows

Core Philosophy

SPARC methodology emphasizes:

  • Systematic Approach: Structured phases from specification to completion
  • Test-Driven Development: Tests written before implementation
  • Parallel Execution: Concurrent agent coordination for 2.8-4.4x speed improvements
  • Memory Integration: Persistent knowledge sharing across agents and sessions
  • Quality First: Comprehensive reviews, testing, and validation
  • Modular Design: Clean separation of concerns with clear interfaces

Key Principles

  1. Specification Before Code: Define requirements and constraints clearly
  2. Design Before Implementation: Plan architecture and components
  3. Tests Before Features: Write failing tests, then make them pass
  4. Review Everything: Code quality, security, and performance checks
  5. Document Continuously: Maintain current documentation throughout

Development Phases

Phase 1: Specification

Goal: Define requirements, constraints, and success criteria

  • Requirements analysis
  • User story mapping
  • Constraint identification
  • Success metrics definition
  • Pseudocode planning

Key Modes: researcher, analyzer, memory-manager

Phase 2: Architecture

Goal: Design system structure and component interfaces

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sparc-methodology is a skill published in the GitHub repository ruvnet/RuView (98,818 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 6,084 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
