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

The only behavioral claim, 'read-only', merely restates what the annotations already declare (readOnlyHint=true, destructiveHint=false, idempotentHint=true). It adds no new context such as auth requirements, workspace scoping behavior, or what 'current' means when no schedule exists.

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 short sentences, front-loaded with the action and endpoint. The trailing 'Limitations: read-only' sentence is largely redundant with the annotations, which is the only wasted space.

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 read-only getter with no output schema, the definition is minimally sufficient: an agent knows what it fetches and where. But it omits what the returned schedule contains and when account_id becomes mandatory, leaving meaningful gaps for a 6-parameter tool.

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 coverage is 83%, so the schema already documents base_url, api_token, account_id, access_token, and app_password. The description adds nothing about user_id semantics or the multi-workspace condition noted in the schema. Baseline 3 applies when the schema carries the 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 and resource ('Gets the current schedule for a user') and pins down the scope with 'current', which distinguishes it from the sibling list_schedules. However, it never contrasts itself with get_schedule, so an agent must infer the difference from the name alone.

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?

There is no when-to-use guidance and no mention of alternatives such as get_schedule or list_schedules. The endpoint path is quoted but that is not usage guidance. An agent gets no help deciding between this and the other schedule read tools.

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