How does this skill handle low-confidence assumptions?

The skill follows a 'Stop and Ask' process, requiring the model to present alternatives to the user for clarification rather than making a commitment to a specific interpretation.

Can this skill improve my documentation and testing?

Yes, by identifying assumptions, it provides a clear roadmap for what needs to be documented in comments, enforced via types (like TypeScript), or covered by unit tests.

Why is surfacing assumptions important for AI coding?

AI models often make silent interpretations of requirements; surfacing assumptions forces these to be explicit, preventing bugs caused by incorrect 'guesses' made by the model during code generation.

When is the best time to trigger the Surface Assumptions skill?

It is most effective when used during the planning phase before writing new code, or during a code review phase to audit the logic of existing snippets.

安全与测试

Identifies and validates hidden technical assumptions to prevent logic errors and edge-case bugs before implementation.

The Surface Assumptions skill addresses the most common category of AI coding errors: models making incorrect assumptions and proceeding without verification. By forcing an explicit audit of input shapes, state requirements, environmental dependencies, and business logic, this skill ensures that Claude clarifies ambiguous requirements rather than guessing. It provides a structured framework for categorizing assumptions by confidence and impact, leading to more robust, production-ready code with fewer runtime failures and better-handled edge cases.
