What problem does it solve?
This skill solves the problem of poorly defined implementation plans by enforcing a rigorous, read-only exploration phase that ensures architectural decisions are grounded in actual repository state before any code is written.
Core Features & Use Cases
- Durable Planning: Creates a standardized .ultraplan/plan.md file that serves as a single source of truth for the implementation.
- Grounded Exploration: Automatically scans the codebase to identify existing utilities, patterns, and dependencies to reuse, preventing redundant work.
- Adversarial Review: Supports high-risk change validation by comparing proposed plans against architectural best practices and potential failure modes.
