hf_search_models

Search HuggingFace models using semantic network and fuzzy matching, with filters for task, author, library, and popularity.

Instructions

Search HuggingFace models using navigational semantic network + fuzzy matching.

Combines three layers:
- Network: Bank-position constraints + anchor similarity (if models indexed)
- Fuzzy: String matching on model IDs, tags, descriptions
- Structured: HF API filters for task, author, library, popularity

Args:
    query: Natural language search query (e.g. "small code model with tool-calling")
    task: HuggingFace task filter (e.g. "text-generation", "text-classification")
    author: Filter by model author/org (e.g. "meta-llama", "mistralai")
    library: Filter by library (e.g. "transformers", "gguf", "diffusers")
    min_likes: Minimum number of likes
    min_downloads: Minimum number of downloads
    limit: Number of results to return (default 20)
    candidate_limit: How many candidates to fetch from HF API (default 500)

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses the three-layer search behavior (network, fuzzy, structured) and the combination approach. Since no annotations exist, it carries the full burden and does so well, though it misses details on rate limits, authentication, or potential side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with bullet points for the three layers and a clear Args list. However, the Args section is somewhat verbose and could be more concise without losing clarity. Overall, it earns its length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (8 params, 1 required) and presence of output schema, the description covers the search mechanism, all parameters, and examples. It lacks details on pagination, error handling, or return structure, but the output schema partly fills that gap. Adequate for most use cases.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description's 'Args' section provides thorough explanations for all 8 parameters, including examples (e.g., 'small code model with tool-calling' for query), defaults, and context for filters like task and author. This fully compensates for the missing schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it searches HuggingFace models using a combination of three distinct layers (navigational semantic network, fuzzy matching, structured HF API filters). This specific verb+resource combination distinguishes it from sibling tools like search_models or navigate_models, which may use simpler approaches.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for semantic search but does not provide explicit guidance on when to use this tool versus alternatives (e.g., simpler search_models). No when-not or alternative tool mentions are included.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
