trmnl_replace_playlist_item_schedule

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

Annotations already declare this as destructive, idempotent, open-world, and non-read-only. The description adds only that it changes remote state and should stay within authorized scope; it does not explain what happens to the previous schedule or any side effects. With annotations covering the main safety profile, this is adequate but not rich.

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 short and front-loads the main action. The extra generic sentence about changing remote state is somewhat redundant with annotations, but the overall size is appropriate.

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 destructive, open-world mutation with nested request body fields and no output schema, the description omits important context about replacement behavior, body structure, and the profile parameter. It is not complete enough to guide safe invocation beyond the basic purpose.

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 only 33%, so the description should compensate, but it does not explain the body fields, profile selection, or the nested schedule structure. It only implies item_id through the endpoint path and does not clarify required body semantics.

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 states a specific verb and resource: replace the schedule controlling when a playlist item is allowed to display. It also gives the underlying PUT endpoint, making the operation precise enough to distinguish it from the sibling get_playlist_item_schedule.

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?

It gives a security restriction ('Run only within the user-authorized scope') but does not explain when to use this instead of getting or updating the playlist item. There is no explicit comparison to alternatives such as trmnl_get_playlist_item_schedule or trmnl_update_playlist_item.

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