create_a_calendar_feed

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

Annotations already provide idempotentHint=false, destructiveHint=false, readOnlyHint=false. The description reinforces non-idempotency by warning that calling twice may create duplicates, which adds some value. However, no information about permissions, side effects, or limits beyond what annotations convey.

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 concise with three short lines, front-loading the purpose. It uses helpful icons and HTTP method. No unnecessary words, though it could be slightly more structured.

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 creation tool without an output schema, the description should mention what is returned (e.g., the created feed). It only states it creates a new record and is not idempotent. Additionally, no guidance on how it relates to sibling tools like list_all_calendar_feeds or update_a_calendar_feed.

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% as each property in the body has a description. The description does not add any additional parameter semantics beyond what the schema already provides.

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 clearly states the tool creates a calendar feed (verb+resource) and mentions it creates a new record. However, it does not distinguish from sibling tools like update_a_calendar_feed or list_all_calendar_feeds beyond the verb, though the name itself is clear.

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?

No guidance on when to use this tool versus alternatives like update_a_calendar_feed or remove_a_calendar_feed. The only usage hint is the non-idempotency warning, but no context about prerequisites or appropriate scenarios.

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