Scored across 4 tools
hf_whoami is clearly distinct, but hf_fs contains search, stat, and ls commands that overlap with hub_repo_search and hub_repo_details for repo discovery and metadata. The descriptions provide some guidance, yet boundaries between resource discovery via hf_fs and the dedicated hub_* tools remain blurry, risking misselection.
All names use snake_case, but the set mixes hf_ and hub_ prefixes and does not follow a consistent verb_noun pattern (e.g., hf_fs, hf_whoami, hub_repo_details, hub_repo_search). The naming is readable but not predictable as a unified convention.
Four tools is within a reasonable range, and hf_fs acts as a dense multi-command interface that covers many operations. The count is slightly lean for the broad Hugging Face domain, but each tool earns its place without obvious redundancy.
The server appears designed for read-only Hub exploration and covers authentication inspection, repo search, repo details, dataset preview, and filesystem-style file access. Write operations (create repo, upload, delete) are absent, but if read-only is intended, the surface is mostly complete with only minor gaps like content search.
When to use: Hugging Face Hub models, datasets, Spaces, collections, papers, daily papers, today's trending models, current paper leaderboard, docs, and repository files.
Examples: {"operations":[{"cmd":"ls","args":["hf://models/trending","--limit","10"]}]} {"operations":[{"cmd":"ls","args":["hf://papers/trending"]}]} {"operations":[{"cmd":"ls","args":["hf://papers/daily/latest"]}]} {"operations":[{"cmd":"cat","args":["hf://papers/2501.00001/paper.md"]}]} {"operations":[{"cmd":"search","args":["hf://models","--tag","base_model:finetune:org/repo"]}]}
Use hf_fs for Hugging Face Hub filesystem operations. Call it with operations, an array of {cmd, args} items; multiple operations may be submitted together.
Usage: {"operations":[{"cmd":"ls","args":["hf://models/org/repo"]}]}
Grammar; each string below is one args array item: ls URI [--recursive] [--glob GLOB] [--type TYPE] [--sort SORT] [--limit N] cat URI [--offset N] [--max-bytes N] attach URI [--max-bytes N] stat URI find URI [--name GLOB] [--path GLOB] [--type TYPE] [--limit N] search URI [QUERY] [--type TYPE] [--sort SORT] [--tag TAG] [--kind mcp] [--limit N]
COMMAND = ls|cat|attach|stat|find|search. TYPE = file|dir|repo|bucket|collection|paper|link. SORT = createdAt|downloads|likes|lastModified|likes30d|trendingScore|mainSize|id|trending|upvotes. URI is a canonical hf:// URI. QUERY and GLOB are each one string.
Use search for resource discovery, not repository-content search; ls for a known directory, find for recursive file discovery by name/path (not file contents), stat for filesystem metadata or an uncertain target type, cat for text contents, and attach for a complete JPEG, PNG, or WebP image. When the request gives an exact text-file URI, use cat directly; do not add ls or stat first. stat does not read the contents of JSON, Markdown, or other text files.
Search scopes: hf://models[/OWNER], hf://datasets[/OWNER], hf://spaces[/OWNER], hf://collections[/OWNER], hf://papers, and hf://docs[/...]. Repository and repository-file scopes are not supported: search a resource root or owner scope to discover resources; use find for file discovery within a repository or cat for a known text file. Paper and documentation search require QUERY. --tag filters models, datasets, and Spaces by Hub tag (repeatable; all must match) and applies only to hf://models|datasets|spaces[/OWNER]; omit QUERY when the tag already identifies the target, because QUERY also filters repository names. Derived models carry base_model:ID and base_model:RELATION:ID tags, where RELATION is finetune, adapter, merge, or quantized. --kind applies only to hf://spaces[/OWNER]; the only valid --kind value is mcp, which selects MCP Spaces. Tag families are documented at hf://README.md. Use ls hf://models/trending, hf://datasets/trending, hf://spaces/trending, or hf://papers/trending for trending listings. hf://papers/ID is a paper directory, not paper text. Use cat hf://papers/ID/paper.md for paper text and cat hf://papers/ID/metadata.json for metadata. No preliminary listing is needed for these known paths. Use ls hf://papers/ID to discover other resources. Omit --limit, --sort, and --type unless the request requires them. Limits and path-specific behavior are documented at hf://README.md. Issue one hf_fs call.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=true, so safety is covered. The description adds genuinely new behavior: unsupported scopes ("Repository and repository-file scopes are not supported"), the fact that --tag only applies to models/datasets/spaces, that --kind only takes the value mcp, and that limits are documented externally at hf://README.md. It omits auth requirements, which keeps it out of the top band.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Well front-loaded with "When to use", then examples, grammar, and routing rules in labeled blocks. It is long but justified by six subcommands and a non-trivial grammar, though some content is redundant (two example blocks; the search-scope caveat is restated in prose and again in the schema's args description) and the pointer to hf://README.md is repeated.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so return values need no explanation. Given the tool's complexity (six commands, URI grammar, flag scoping), the description covers invocation shape, routing, scope legality, and anti-patterns thoroughly. Nothing an agent needs to call it correctly is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is low, but the description fully compensates: it documents the {cmd, args} shape, the per-command args grammar (ls/cat/attach/stat/find/search with every flag), the URI requirement, the TYPE and SORT enumerations, and semantic constraints on --tag and --kind. This is far more than the schema conveys.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description names a concrete verb+resource ("Use hf_fs for Hugging Face Hub filesystem operations") and enumerates the exact resource families it reaches (models, datasets, Spaces, collections, papers, docs, repository files), plus the six commands available. It never names or contrasts with the sibling tools (hf_whoami, hub_repo_details, hub_repo_search), so an agent must infer the boundary versus hub_repo_search on its own. Clear purpose, missing sibling differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It gives explicit per-command routing ("ls for a known directory, find for recursive file discovery by name/path (not file contents), stat for filesystem metadata... cat for text contents, attach for a complete JPEG, PNG, or WebP image") plus a negative exclusion ("search for resource discovery, not repository-content search") and an anti-pattern ("do not add ls or stat first"). When to use which command is fully specified with when-not cases.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Inspect the current Hugging Face authentication context, including the account, visible organization memberships, and credential access details. Read-only and never returns credential values.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds genuinely useful non-obvious behavior: it will never return credential values, which prevents an agent from expecting secrets/tokens in the response.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two tight sentences, with the core purpose front-loaded and the important read-only/credential clarification immediately following. Every phrase earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a no-parameter, read-only introspection tool with an output schema present, the description is complete. It covers what the call inspects, the read-only safety profile, and the credential-privacy behavior; nothing else is needed to invoke it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema is empty with zero parameters, so parameter semantics are not applicable. The baseline for a zero-parameter tool is 4, and the description does not need to compensate for any parameter documentation gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Inspect') and identifies the resource ('current Hugging Face authentication context'), then enumerates the main outputs: account, visible organization memberships, and credential access details. This clearly differentiates it from the sibling repository/file tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The context is clear: use this when the agent needs to determine the current logged-in Hugging Face identity or authentication scope. It doesn't explicitly name alternatives, but none of the siblings overlap in function, so the omission is minor.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Get details for one or more Hugging Face repos (model, dataset, or space). Auto-detects type unless specified. For datasets, use operations: overview, dataset_structure, dataset_preview. Use dataset_structure first to discover configs, splits, sizes, and schema. Use dataset_preview only when config and split are known, unless the dataset has a single config/split.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Row count for dataset_preview. Defaults to 5 and is clamped to 1-100. | |
| split | No | Dataset Viewer split. Required for dataset_preview when the dataset has multiple config/split options. Discover via dataset_structure. | |
| config | No | Dataset Viewer config. Required for dataset_preview when the dataset has multiple config/split options. Discover via dataset_structure. | |
| offset | No | Row offset for dataset_preview. Defaults to 0. | |
| repo_ids | Yes | Repo IDs for (models|dataset/space) - usually in author/name format (e.g. openai/gpt-oss-120b) | |
| repo_type | No | Specify lookup type; otherwise auto-detects | |
| operations | No | Details to return. Defaults to ["overview"]. For datasets, prefer ["overview", "dataset_structure"] first; then call ["dataset_preview"] with config and split. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint=true and destructiveHint=false, and the description adds behavioral context by explaining auto-detection of repo type and the recommended ordering of dataset operations. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences long, beginning with the core purpose and followed by targeted guidance for datasets. No redundant or filler content; each sentence earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 7 parameters and no output schema, the description covers the dataset workflow well, including discovery and preview conditions. It does not detail return shapes, but given the read-only nature and strong annotations, this is sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers 100% of parameters with descriptions, so baseline is 3. The description adds semantic value by linking operations to parameters (e.g., dataset_structure before dataset_preview, using config/split only when known), exceeding the schema's per-parameter descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get details for one or more Hugging Face repos (model, dataset, or space)' with a specific verb, resource, and scope. It differentiates from siblings like hub_repo_search by focusing on details retrieval and mentions auto-detection of repo type.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides clear workflow for datasets: 'Use dataset_structure first to discover configs, splits, sizes, and schema. Use dataset_preview only when config and split are known.' This gives explicit context, though it does not mention when NOT to use the tool or direct alternatives among sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Search Hugging Face repositories with a shared query interface. You can target models, datasets, spaces, or aggregate across multiple repo types in one call. Include links to repositories in your response.
| Name | Required | Description | Default |
|---|---|---|---|
| sort | No | Sort order (descending): trendingScore, downloads, likes, createdAt, lastModified | |
| limit | No | Maximum number of results to return per selected repo type | |
| query | No | Search term. Leave blank and specify sort + limit to browse trending or recent repositories. | |
| author | No | Organization or user namespace to filter by (e.g. 'google', 'meta-llama', 'huggingface'). | |
| filters | No | Optional hub filter tags. Applied to each selected repo type (e.g. ["text-generation"], ["language:en"], ["mcp-server"]). | |
| repo_types | No | Repository types to search. Defaults to ["model", "dataset"]. space uses keyword search via /api/spaces. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds context beyond the annotations by stating that the tool can aggregate across multiple repo types and that responses should include links to repositories. This is useful behavioral information, though it doesn't disclose details like rate limits or auth requirements, which are covered by annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the verb and resource. The first sentence defines the tool, and the second elaborates on scope and response format. Every clause is purposeful, with no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
There is no output schema, but the description hints at the output by instructing the agent to include links to repositories. It covers the main capability (searching across repository types) and leaves parameter details to the schema. This is reasonably complete for a search tool, though it could mention sorting/limiting, which the schema already documents.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema covers all 6 parameters with descriptions (100% coverage), so the baseline is 3. The description enhances the repo_types parameter by explaining the ability to target models, datasets, or spaces and aggregate across multiple types in one call, adding meaning beyond the schema's enum list.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Search Hugging Face repositories' with a specific verb and resource. It also differentiates from siblings by mentioning targeting models, datasets, and spaces or aggregating across multiple repo types, making the purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context that this tool is for searching across repo types and can aggregate multiple types in one call. It does not explicitly name alternatives or exclusions, but the context of a shared query interface and the sibling names (e.g., hub_repo_details) make the appropriate usage evident.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
