SnowSure — Snow & Ski

Save a resort

save_resort

Idempotent

Add a resort to the signed-in user's My Mountains, the list of resorts they follow. Requires a SnowSure user access token (OAuth). The slug must be a real SnowSure resort.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`slug`	No	Resort slug or name, e.g. "portillo" or "Portillo". Required unless `resort` is given.
`resort`	No	Same as `slug`: the resort slug or name. Pass either one.

Output Schema

TableJSON Schema

Name	Required	Description	Default
`markdown`	No	Human-readable markdown summary of the tool result (may be omitted when structuredContent carries a typed payload; content[0].text always has the prose).

A3.8/5.0

Behavior4/5

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

Annotations already cover safety (readOnlyHint=false, destructiveHint=false, idempotentHint=true, openWorldHint=false), so the bar is lower. The description still adds two genuine behavioral facts not in the annotations: an OAuth token is required, and the slug must correspond to a real SnowSure resort (an input-validation constraint). It does not restate what an already-saved resort does, but idempotentHint covers that.

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

Conciseness5/5

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

Two short sentences, front-loaded with the action and target collection before the prerequisites. No filler or repetition.

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?

An output schema exists so return values need not be explained, and annotations carry the safety profile. The description supplies the auth requirement and input-validation rule, leaving little an agent would need to infer before calling.

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

Parameters3/5

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

Schema coverage is 100% and both parameters (slug/resort aliases) are fully documented in the schema, so baseline is 3. The description adds only the validation constraint that the slug must be a real resort; it does not explain the slug/resort aliasing, which the schema already handles.

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

Purpose4/5

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

States a specific verb and resource ('Add a resort to the signed-in user's My Mountains') and even names the target collection, so the write operation is unambiguous. It does not explicitly distinguish itself from the near-identical siblings list_saved_resorts and remove_saved_resort, but the verb makes the direction obvious.

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?

Gives a prerequisite (OAuth access token required) which is useful context for invocation, but offers no explicit when-to-use guidance relative to list_saved_resorts or remove_saved_resort. Usage is implied by the name rather than stated.

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