speckit-workflow

speckit-workflow is a skill for Claude Code from tzachbon/smart-ralph. It costs 30 tokens per session (1,855 once invoked), scanned A, original, MIT.

A guide to SpecKit, a constitution-driven workflow for developing features through specification, technical planning, task creation, and implementation. A project constitution is a document containing its development principles and rules.

In plain words
What is it for?
Use it to understand or run SpecKit projects, organize feature documents, connect specifications to project principles, and manage the workflow from idea to implementation.
Why use it?
It gives teams a shared process and makes project rules explicit instead of relying on unwritten conventions. This helps keep feature decisions and quality checks consistent.

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

speckit-workflow 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 8d 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.

SpecKit Workflow

The SpecKit methodology is a constitution-driven approach to feature development. It ensures consistency across features by grounding all decisions in project principles.

Core Philosophy

Constitution First: Every feature is designed against the project's constitution - a living document of principles, constraints, and standards.

Governance Over Convention: Rather than implicit patterns, SpecKit makes governance explicit through:

  • Constitution principles (MUST, SHOULD, MAY)
  • Feature specifications tied to principles
  • Quality checklists as "unit tests for requirements"
  • Consistency analysis across artifacts

Feature ID System

Features use auto-incremented 3-digit IDs:

  • 001-user-auth
  • 002-payment-gateway
  • 003-notification-system

Benefits:

  • Natural ordering in filesystem
  • Easy reference in commits/PRs
  • Prevents naming conflicts

Workflow Phases

Phase 1: Constitution (/speckit:constitution)

Establish or update project-wide principles.

Inputs: Project context, team preferences Outputs: .specify/memory/constitution.md

Constitution sections:

  • Identity: Project name, purpose, core domain
  • Principles: MUST/SHOULD/MAY rules
  • Technology Stack: Languages, frameworks, tools
  • Patterns: Architecture, naming, error handling
  • Quality Standards: Testing, performance, security

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.

speckit-workflow is a skill published in the GitHub repository tzachbon/smart-ralph (535 stars, last pushed 5d ago), licensed MIT. It adds 30 tokens to every session and 1,855 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
