SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Navigating a large skill library of 88 entries (7 cognitive atoms, paper pipeline, research methodology, and AI/ML tools) is slow and error-prone without a structured index. This Skill provides a navigation layer that filters the core research stack by layer, query, and context, returning a structured list of matching skills. ## Core Features & Use Cases - Query-Based Skill Retrieval: Accepts layer, query, and context inputs and returns a skill_list of matching skills with names and descriptions, validated against the IO contract. - Contract-Enforced Error Handling: Returns an empty list with search suggestions when no match exists, and returns an error status with recovery advice when required parameters are missing instead of silently executing. - Use Case: A researcher asks which skills relate to hypothesis generation; the index returns hypothesis-generation and data-driven-hypothesis with descriptions, ready for the task router to invoke. ## Quick Start Ask the agent to search the core layer index for skills matching your research query, for example by providing layer 'core' and query '假设生成' to retrieve hypothesis-related skills.

FAQPage Schema
How do I search for skills in a large skill library?

Provide a layer name, a query string, and a context dictionary to the index, which returns a filtered skill_list of matching entries with names and descriptions. The query supports both English and Chinese keywords matched against the 88-skill catalog.

What is a layer index in a skill-based agent architecture?

A layer index is a navigation component that maps all skills in one architectural layer, such as the core research stack, into a searchable catalog. It lets a task router locate the right cognitive atom or tool without scanning every skill file.

What happens when a skill search returns no matches?

The index returns an empty skill_list along with a suggestion message containing context and recovery advice, such as checking keyword spelling or switching to English terms. It never fabricates entries or raises an unhandled error.

What happens if required input parameters are missing?

The index validates that layer, query, and context are all present before executing. If any parameter is missing, it returns an error status code with the missing parameter name and recovery guidance instead of silently running.

How is the skill index kept consistent with the actual skill catalog?

Golden test cases verify that index entries correspond one-to-one with the 88 skills listed in the SKILL.md catalog, with no omissions or duplicates. Any drift between the index and the catalog fails verification and must be synchronized.
