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

Annotations already declare destructiveHint=true, which tells the agent this is a mutating operation, so the description need not re-establish that. It adds the REST mapping (POST /links/{id}/duplicate) but says nothing about whether the original link is modified, what the new copy inherits, or what the caller receives back. Adequate but thin for a mutating tool.

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, zero filler, with the operation stated first and the API endpoint appended as reference. Nothing could be removed without losing information.

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 one-parameter tool with no output schema, the main missing piece is what the duplicate response contains (e.g., whether the new link id is returned), which the agent would need to chain into savvycal_get_link or savvycal_toggle_link. Everything else an agent needs to invoke it is present.

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 the single parameter is already fully documented as 'The scheduling link id to duplicate.' The description only restates that an existing link is the target and adds no id format or source guidance, so baseline 3 applies.

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 ('Create a copy of an existing scheduling link') and pins down the exact operation, which is plainly distinguishable from the read-oriented siblings like savvycal_get_link and savvycal_list_links. An agent can identify the operation without opening the schema.

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, no prerequisites (e.g., whether the id must come from savvycal_list_links), and no statement of when duplication is preferable to any alternative. Usage can only be inferred from the tool name and the word 'copy'.

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