SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Phase planning often yields circular dependencies, misordered tasks, and gaps between ACs and implementations. This Skill catches those issues before implementation, saving time and preventing rework.

Core Features & Use Cases

Detects circular dependencies in tasks.md and provides actionable fixes.
Verifies that all declared dependencies appear earlier in the sequence or are resolvable via resume state.
Checks task sizing heuristics to identify XL tasks that should be split.
Ensures infrastructure tasks precede feature tasks to avoid deployment blockers.
Generates tasks-validation.md in .claude/feature-state/{slug}/ and resumes work where possible.

Quick Start

Run the validator after generating tasks to produce tasks-validation.md in the state directory.

FAQPage Schema

How do I detect circular dependencies in a task plan before implementation?▼

To detect circular dependencies in a task plan, validate the generated tasks to enforce cycle detection and correct execution order, producing a validation report with actionable fixes for broken workflows.

What is topological sorting used for in task dependency validation?▼

Topological sorting during task dependency validation ensures all declared dependencies appear earlier in the sequence, verifying correct execution order and preventing misordered tasks in end-to-end feature workflows.

How do I check if my feature tasks are too large and need splitting?▼

To check if feature tasks need splitting, apply task sizing heuristics during validation to identify XL tasks, ensuring they are properly sized before implementation begins.

Can I validate that infrastructure tasks precede feature tasks in my workflow?▼

Yes, you can validate infrastructure sequencing by enforcing checks that ensure infrastructure tasks precede feature tasks, preventing deployment blockers and misordered execution in feature workflows.

Does task plan validation verify acceptance criteria coverage?▼

Yes, task plan validation verifies AC coverage to prevent gaps between acceptance criteria and implementations, catching missing requirements before development starts.

How do I resume a task validation process after an interruption?▼

To resume task validation after an interruption, state persistence saves progress in a feature-state directory, allowing the validator to resume work where possible using resolvable resume state.
