What does this skill do?

The Skill Development Blueprint transforms a single-line objective into a step-by-step implementation plan, designed for complex engineering projects that span multiple sessions and agents. Each step includes self-contained context, tasks, verification commands, and output criteria, so that any agent can execute it from scratch without losing track of the process. Additionally, a sub-agent using the most powerful model performs an adversarial review for anti-patterns before saving the plan.

Split into Pull Requests
Break down a large feature into multiple PRs with a clear and verifiable order of dependencies.
Refactoring or Multi-Session Migration
Plan refactoring or migrations that require multiple work sessions without losing context between them.
Multi-Stakeholder Coordination
Coordinates parallel workflows among different sub-agents by assigning model levels and rollback strategies.
Adversarial Review
A sub-agent using the most powerful model reviews the plan against a list of anti-patterns before finalizing it.

Usage examples

🔀 Database Migration
/blueprint miapp "migrate database to PostgreSQL"
🤖 Multi-agent plugin system
/blueprint chatbot "extract LLM providers into a plugin system"
🔄 Multi-session refactoring
/blueprint api "Refactor the authentication layer to OAuth2"
🔀 Extensive functionality in PRs
/blueprint dashboard "Implement a real-time analytics dashboard using WebSockets"

Features

Autonomous context per step Each step of the plan includes a background summary, a list of tasks, verification commands, and acceptance criteria.
Dependency graph Assign dependency edges, parallel or serial order, and the model level to be used for each step.
Automated Adversarial Review A sub-agent using the most powerful model reviews the plan for anti-patterns and corrects critical findings.
Preliminary Research for the Project Analyze the project structure, build files, Git status, and default branch before designing the plan.
Output in plain Markdown Generate a file in the `plans/` directory containing the complete breakdown, the dependency graph, and the plan's mutation protocols.

Frequently asked questions

Use it when you need to split a large feature into multiple PRs, plan a multi-session refactor or migration, or coordinate parallel workflows among sub-agents. Do not use it for tasks that can be completed in a single PR or with fewer than 3 tool calls.
No additional MCPs are required. The skill runs within Claude Code or Cowork and uses standard tools for accessing the file system and Git.
The skill assigns dependency edges between steps. When two steps are not dependent on each other, they are marked as parallel. The final summary indicates the level of parallelism detected.
Yes. The Markdown file includes protocols for modifying the plan to alter steps, dependencies, or rollback strategies without disrupting the self-contained context.
