specify is a command for Claude Code from athola/claude-night-market. It costs 15 tokens per session (2,588 once invoked), scanned A, original, MIT.

A requirements-writing command that turns a project brief into a detailed specification with functional requirements and acceptance criteria.

In plain words
What is it for?
Use it to define what a feature or project must do, document technical and non-technical requirements, set boundaries, and prepare work for planning.
Why use it?
It replaces vague project descriptions with requirements that can be checked during implementation.

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

specify 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 5d 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.

Attune Specify Command

Transform project briefs into structured, testable specifications with functional requirements and acceptance criteria.

When To Use

Use this command when you need to:

  • Transform brainstorm output into detailed specification
  • Create testable requirements from project brief
  • Define acceptance criteria for implementation
  • Document functional and non-functional requirements
  • Establish scope boundaries before planning

When NOT To Use

Avoid this command if:

  • Still exploring problem space (use /attune:brainstorm first)
  • Already have detailed specification (use /attune:blueprint instead)
  • Need to refine existing spec (edit specification document directly)
  • Making architectural decisions without requirements (brainstorm first)

Usage

# Create specification from brainstorm output
/attune:specify

# Specify with custom input
/attune:specify --input docs/project-brief.md

# Generate specification for specific feature
/attune:specify --feature "user authentication"

What This Command Does

  1. Loads project brief from brainstorm phase
  2. Invokes specification skill with spec-kit integration
  3. Generates detailed requirements using structured format
  4. Creates testable acceptance criteria
  5. Produces specification document for planning phase

Integration with Spec-Kit

When spec-kit plugin is available:

  • Uses Skill(spec-kit:spec-writing) for specification methodology
  • Applies structured requirement templates
  • Ensures testable acceptance criteria

Without spec-kit:

  • Falls back to attune's native specification skill
  • Provides similar step-by-step approach
  • Documents requirements systematically

Workflow

# 1. Invoke specification skill
Skill(attune:project-specification)

# 2. Transform brief into structured spec:
#    - Functional requirements
#    - Non-functional requirements
#    - Acceptance criteria
#    - Technical constraints
#    - Dependencies

# 3. Generate specification document
#    - Saved to docs/specification.md
#    - Includes all requirements with testability

# 4. Workflow auto-continues (see below)
