Mechanism

When It Triggers · How It Works · What It Produces

Breaks down how the skill works and what it produces, so you can quickly judge whether it fits your scenario and value.

Trigger

When you have a spec and need implementable units
When a task feels too large or vague to start
When work needs to be parallelized

Mechanism

Enter plan mode: read-only analysis, no code writing
Identify dependency graph: database → API → frontend, build bottom-up
Vertical slicing: each task delivers a complete end-to-end path
Task template: description, acceptance criteria, verification, dependencies, files, scope estimate

Outcome

Plan document (tasks/plan.md) and task list (tasks/todo.md) with ordered, executable tasks

Use Cases

Two Typical Use Cases

Scenario 01

Feature Spec to Development Task Breakdown

After a feature spec is complete, the agent decomposes it into an executable task list, analyzing dependencies, organizing tasks by vertical slices, ensuring each task is small enough for one session but delivers independent value.

Scenario 02

Parallel Development Task Allocation

When multiple developers or agents work in parallel, the agent identifies parallelizable task groups via dependency graph analysis, assigning independent tasks to different executors to maximize parallel efficiency.

You May Also Need These Skills

api-and-interface-design

Guides agents to design stable, hard-to-misuse public interfaces using contract-first principles. Covers REST, GraphQL, module boundaries, component props, emphasizing Hyrum's Law, One-Version Rule, error semantics, and boundary validation. Produces consistent, maintainable, well-documented interface specifications.

Workflow

browser-testing-with-devtools

Browser testing skill that gives agents live browser runtime visibility via Chrome DevTools MCP. Supports DOM inspection, console log capture, network request analysis, performance profiling, and visual output verification. Bridges the gap between static code analysis and live browser execution.

CLI Manual

ci-cd-and-automation

CI/CD automation skill that guides agents to set up and maintain automated build and deployment pipelines. Emphasizes shifting quality gates left, integrating tests, lint, type checking, and build verification into every change. Follows the "smaller is faster is safer" principle with frequent small releases.

Workflow

code-review-and-quality

Code review and quality skill that guides agents to conduct multi-axis code reviews covering correctness, design, maintainability, security, and performance. Emphasizes change sizing (~100 lines), severity labels (Nit/Optional/FYI), and splitting strategies to ensure code quality before every merge.
