sparc-methodology

sparc-methodology is a skill for Claude Code from Soulcynics404/AgentForge. It costs 79 tokens per session (759 once invoked), scanned A, a copy of sparc-methodology, MIT.

A five-stage development method: specification, pseudocode, architecture, refinement, and completion. It gives complex software work a structured path from requirements to finished code.

In plain words
What is it for?
Use it for new features, architectural changes, system redesigns, integrations, and other complex implementations.
Why use it?
It helps reduce uncertainty before coding by defining requirements, sketching the solution, and planning the system structure first.

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 4d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/sparc-init.sh, scripts/sparc-review.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 Skill

Purpose

SPARC development workflow: Specification, Pseudocode, Architecture, Refinement, Completion. A structured approach for complex implementations that ensures thorough planning before coding.

When to Trigger

  • new feature implementation
  • complex implementations
  • architectural changes
  • system redesign
  • integration work
  • unclear requirements

When to Skip

  • simple bug fixes
  • documentation updates
  • configuration changes
  • well-defined small tasks
  • routine maintenance

Commands

Specification Phase

Define requirements, acceptance criteria, and constraints

npx @claude-flow/cli hooks route --task "specification: [requirements]"

Example:

npx @claude-flow/cli hooks route --task "specification: user authentication with OAuth2, MFA, and session management"

Pseudocode Phase

Write high-level pseudocode for the implementation

npx @claude-flow/cli hooks route --task "pseudocode: [feature]"

Example:

npx @claude-flow/cli hooks route --task "pseudocode: OAuth2 login flow with token refresh"

Architecture Phase

Design system structure, interfaces, and dependencies

npx @claude-flow/cli hooks route --task "architecture: [design]"

Example:

npx @claude-flow/cli hooks route --task "architecture: auth module with service layer, repository, and API endpoints"

Refinement Phase

Iterate on the design based on feedback

npx @claude-flow/cli hooks route --task "refinement: [feedback]"

Example:

npx @claude-flow/cli hooks route --task "refinement: add rate limiting and brute force protection"

Completion Phase

Finalize implementation with tests and documentation

npx @claude-flow/cli hooks route --task "completion: [final checks]"

Example:

npx @claude-flow/cli hooks route --task "completion: verify all tests pass, update API docs, security review"

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
