What Blueprint is
Blueprint is a slash command published in the athola/claude-night-market repository on GitHub, which has about 339 stars. The repository describes itself as: “23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context optimization, research, and multi-LLM delegation. 186 skills, 128 commands, 54 agents.”
A slash command is a reusable prompt saved as a markdown file and run by typing its name after a slash. In Claude Code, custom commands have been merged into skills: a file in .claude/commands/ and a skill folder in .claude/skills/ both create the same kind of command, and existing command files keep working.
Blueprint gives you a repeatable way to run the same instructions without retyping them, optionally with arguments.
How to install Blueprint
Claude Code
- Download blueprint.md from the repository.
- Save it to ~/.claude/commands/ (all projects) or .claude/commands/ (one project). As a skill, you can instead save it as ~/.claude/skills/<name>/SKILL.md.
- Run it by typing / followed by its name.
Claude Cowork
- Turn the command into a skill: create a folder with the file saved as SKILL.md and zip it.
- In Customize → Skills, click +, then upload the ZIP.
- Run it from any task with / and the skill name.
New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.
Inside the source file

Transform specifications into executable implementation plans with system architecture, component design, and dependency-ordered task breakdown.
When To Use
Use this command when you need to:
- Convert specification into implementation plan
- Design system architecture from requirements
- Break down work into dependency-ordered tasks
- Estimate effort and plan sprints
- Define component interfaces and data flow
- Create concrete roadmap for execution
When NOT To Use
Avoid this command if:
- No specification exists yet (use /attune:specify first)
- Still defining requirements (complete specification phase)
- Ready to execute existing plan (use /attune:execute instead)
- Adjusting running project (update plan incrementally)
Usage
# Create plan from specification
/attune:blueprint
# Plan with custom input
/attune:blueprint --input docs/specification.md
# Focus on specific component
/attune:blueprint --component "authentication"What This Command Does
- Loads specification from specify phase
- Invokes planning skill with superpowers integration
- Designs system architecture (components, interfaces, data flow)
- Breaks down into tasks with dependencies and estimates
- Produces implementation plan for execution phase
Integration with Superpowers
When superpowers plugin is available:
- Uses Skill(superpowers:writing-plans) for structured planning
- Applies dependency analysis
- Creates checkpoint-based execution flow
Without superpowers:
- Falls back to attune's native planning skill
- Provides similar step-by-step approach
- Documents tasks systematically
Workflow
# 1. Invoke planning skill
Skill(attune:project-planning)
# 2. Design architecture:
# - System components
# - Component interfaces
# - Data flow diagrams
# - Technology selections
# 3. Break down into tasks:
# - Development tasks with dependencies
# - Testing tasks
# - Deployment tasks
# - Documentation tasks
# 4. Generate implementation plan
# - Saved to docs/implementation-plan.md
# - Includes architecture + task breakdown
…Workflow Continuation Protocol (MANDATORY)
After planning completes successfully, auto-proceed to the next phase unless --standalone was specified:
- Verify artifact: Confirm docs/implementation-plan.md exists and is non-empty
- Checkpoint message: Display brief summary to user:
Implementation plan complete. Saved to docs/implementation-plan.md.
Proceeding to execution phase...- Auto-invoke next phase:
Skill(attune:project-execution)Bypass Conditions (skip auto-continuation if ANY true):
- --standalone flag was provided
- docs/implementation-plan.md does not exist or is empty
- User explicitly requests to stop after planning

Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
