sparc-pipeline

sparc-pipeline is a skill for Claude Code, Codex from mattmre/EVOKORE-MCP-PUBLIC. It costs 47 tokens per session (677 once invoked), scanned A, original, MIT.

A five-phase development workflow covering specification, pseudocode, architecture, implementation, and completion. Each phase creates a document and must meet defined criteria before the next phase begins.

In plain words
What is it for?
Use it to guide complex feature work from requirements and design through implementation and final quality checks.
Why use it?
It provides a structured path for complex features and prevents implementation from moving ahead without requirements, design, or verification.

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-pipeline 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 9d 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-pipeline — Full SPARC Development Pipeline

Runs all 5 SPARC phases sequentially with mandatory done-criteria gates between each phase. Suitable for features requiring structured, verifiable development.

Usage

/sparc-pipeline "feature name"
/sparc-pipeline "Implement multi-tenant session isolation"

The 5 Phases

Each phase produces a document in docs/session-phases/ and must pass its done-criteria gate before the next phase begins.

Phase 1: Specification

Produces: docs/session-phases/phase_1_<slug>.md

Done criteria gate:

  • All FRs are testable (measurable acceptance criteria)
  • NFRs have numeric thresholds
  • Gherkin scenarios cover happy path + 3 edge cases

Phase 2: Pseudocode

Produces: docs/session-phases/phase_2_<slug>.md

Done criteria gate:

  • Every FR has corresponding pseudocode
  • Error states enumerated (no "TODO: handle errors")
  • Algorithm complexity documented

Phase 3: Architecture

Produces: docs/session-phases/phase_3_<slug>.md

Done criteria gate:

  • All component interfaces defined
  • No circular dependencies
  • ADR written for non-obvious design choices

Phase 4: Refinement (Implementation)

Produces: Working code + tests

Done criteria gate:

  • All Gherkin scenarios from Phase 1 pass as vitest tests
  • TypeScript compiles clean (npx tsc --noEmit)
  • Truth score >= 0.90 (see verification-quality skill)

Phase 5: Completion

Produces: PR with all sections + updated docs

Done criteria gate:

  • CI green (Build + TypeCheck + Tests pass)
  • PR template sections filled (Description, Type of Change, Testing, Evidence)
  • CLAUDE.md updated if any new patterns discovered
  • next-session.md updated

Gate Failure Handling

If a phase fails its gate:

  1. Document the failure reason in the phase file
  2. Fix the gap in the current phase
  3. Re-check the gate criteria
  4. Do NOT proceed to the next phase until the gate passes

Output Summary

At completion, the pipeline produces:

  • 3 phase documents (phase_1, phase_2, phase_3)
  • Working code with full test coverage
  • A merged PR

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.
