Parks Open

OverviewDiscussionsAdmin

Closures, fire bans, advisories, nearby wildfires

parksopen_check_alerts
Read-onlyIdempotent

Use this when checking current closures, fire bans, advisories, or nearby wildfires for one park or system-wide. Run it before recommending a park in summer; these are 'verify before you travel' notices, never a booking or safety claim.

TDQS

A4.3/5.0
Behavior4/5

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

Annotations already establish read-only, open-world, and idempotent behavior, so the description's extra value comes from clarifying that these are 'verify before you travel' notices and 'never a booking or safety claim.' That caveat prevents the agent from overstating what the data means, which is meaningful behavioral context beyond the annotations.

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 front-loaded sentences carry the purpose, the recommended timing, and an important interpretive caveat with zero wasted words. Every clause earns its place in the description.

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

Completeness5/5

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

Given full schema coverage, rich annotations, and an output schema, the description is complete enough for correct invocation. It states what the tool checks, when to run it, the scope options, and how to interpret the results, so nothing essential is missing.

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 description coverage is 100%, so the parameter semantics baseline is 3. The description does add that results can be for 'one park or system-wide,' which aligns with the optional park parameter, but it does not add substantial meaning beyond what the schema already documents.

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 pairs a specific verb, 'checking,' with a concrete resource: current closures, fire bans, advisories, and nearby wildfires, scoped to either one park or system-wide. This clearly differentiates the tool from weather, booking, availability, and park-info siblings without needing to open their schemas.

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

Usage Guidelines4/5

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

The description gives explicit usage context: 'Use this when checking current closures...' and 'Run it before recommending a park in summer.' It does not explicitly name alternative tools or state when not to use it, but the timing and scope guidance is clear enough for an agent to select it confidently.

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