sparc-methodology

sparc-methodology is a skill for Claude Code, Codex from mattmre/EVOKORE-MCP-PUBLIC. It costs 36 tokens per session (561 once invoked), scanned A, original, MIT.

A five-phase method for organising complex software work: specification, pseudocode, architecture, refinement, and completion.

In plain words
What is it for?
Defining requirements, planning algorithms and system structure, implementing changes, testing them, and completing large refactors or integrations.
Why use it?
It breaks unclear or large development tasks into stages with concrete outputs and checks before moving forward.

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 11d 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.

What it actually says

SPARC Methodology Skill

A 5-phase structured development approach that ensures correctness at each stage before proceeding.

Trigger

Use this skill when:

  • Starting a complex feature with unclear requirements
  • Refactoring a large system component
  • Building multi-service integrations
  • Onboarding to an unfamiliar codebase

The 5 Phases

Phase 1: Specification (S)

Output: phase_1_{slug}.md
Produces: Functional Requirements (FR-01..FR-N), Non-Functional Requirements (NFR-01..NFR-N), Gherkin scenarios (Given/When/Then), acceptance criteria.

Done criteria:

  • All FRs are testable
  • NFRs have measurable thresholds
  • Gherkin scenarios cover happy path + top 3 edge cases

Phase 2: Pseudocode (P)

Output: phase_2_{slug}.md
Produces: Language-agnostic algorithm representation, data flow diagram, error handling strategy.

Done criteria:

  • Pseudocode covers every FR
  • Error states enumerated
  • No ambiguous "do magic here" blocks

Phase 3: Architecture (A)

Output: phase_3_{slug}.md
Produces: Component diagram, interface contracts, dependency graph, ADR for key decisions.

Done criteria:

  • All interfaces defined
  • No circular dependencies
  • ADR written for any non-obvious choice

Phase 4: Refinement (R)

Output: Working code + tests
Produces: Implementation iterating from pseudocode, test cases from Gherkin, TypeScript type-safe.

Done criteria:

  • All Gherkin scenarios pass
  • TypeScript compiles clean
  • Truth score >= 0.90

Phase 5: Completion (C)

Output: PR + docs
Produces: PR with all sections filled, docs updated, CLAUDE.md updated if patterns changed.

Done criteria:

  • CI green
  • PR review checklist complete
  • next-session.md updated

Usage

/sparc-spec "{feature name}"     → Runs Phase 1 only
/sparc-pipeline "{feature name}" → Runs all 5 phases sequentially with gate checks
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.
