sixflags_get_park_schedule

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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint, so the safety profile is covered. The description adds only the forward-looking time window ('from today forward') and the home-park default — useful but minimal context beyond the structured fields; nothing about freshness, caching, or how closures are represented.

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?

Three short sentences with no filler: what it returns, the time window, the default, and the planning use case, all front-loaded. Every clause earns its place and nothing is repeated from the schema or annotations.

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 parameterless-required, read-only lookup with no output schema, the description tells the agent what comes back (open/close times), the temporal range, and the default target. Nothing an agent needs in order 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 100%, so both 'days' and 'park' are fully documented in the schema, and the description matches the schema's default-park note without adding range or format detail. Baseline 3 is appropriate when the schema carries the parameter burden.

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?

States a specific verb+resource pair ('Get operating hours (open/close times) for a Six Flags park') with the added temporal scope 'from today forward'. The resource is inherently disjoint from every sibling (wait times, shows, attractions, park list), so an agent can route here without ambiguity, though no sibling is named explicitly.

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?

Gives a concrete use case ('plan what time to arrive and how long you have') and discloses the default-park behavior, which is a real selection signal. It stops short of stating when NOT to use it or pointing to a complementary sibling like sixflags_get_wait_times for same-day planning.

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