cache_base_model

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

With no annotations provided, the description carries full burden and adequately discloses that the tool is a dry run (no network) that emits a command. This prevents misinterpretation as a harmful operation. However, it could mention that no files are modified or that the command is printed to output.

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 a single sentence that is concise and front-loaded with the core purpose. It efficiently communicates the tool's function without unnecessary words, earning a place for its simplicity.

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?

Given the tool's simplicity and the presence of an output schema, the description covers the main intent and behavioral constraint (dry run). However, it lacks parameter guidance and does not detail the output format beyond being a command. This is adequate but leaves gaps for an agent unfamiliar with huggingface-cli.

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 0%, so the description must compensate. It does not explain any parameter (dest, repo_id, revision). An agent must rely on parameter names alone, which may be ambiguous (e.g., 'dest' could be local or remote). The description would benefit from brief parameter clarifications.

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 the tool 'emits the huggingface-cli download command for a base model' and specifies it's a dry run with no network activity. This verb+resource combination is specific and distinguishes it from sibling tools like _mcp_update_base_model which likely performs actual downloads.

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 implies usage for previewing commands via 'dry_run — no network', but it does not explicitly state when to use this tool versus alternatives, nor does it mention when not to use it. No sibling tools are referenced for comparison.

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