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

The readOnlyHint annotation already declares this is a safe read operation, and the description's REST GET reference aligns with that. However, no additional behavioral details are provided (e.g., error handling, authentication, rate limits). With annotations covering the safety profile, this is acceptable but not enriched.

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 one sentence, omits filler, and front-loads the core action. The REST endpoint reference is concise and relevant, adding no waste.

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 simple get-by-id operation with full schema and a read-only annotation, the description is largely complete. It does not describe the response format or error codes, but for this trivial tool, that is not a critical gap.

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?

The schema provides 100% coverage with descriptions for both 'id' and 'include'. The description only repeats the 'by id' notion and adds no new meaning beyond the schema. Baseline 3 applies due to high schema coverage.

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 action ('Get') and the resource ('a single ticket by id'), which distinguishes it from sibling tools like freshdesk_list_tickets and freshdesk_search_tickets. The REST endpoint reference reinforces the specific operation.

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?

The description implies the appropriate usage scenario: when you have a specific ticket ID and need that one ticket. It does not explicitly mention alternatives, but the 'by id' wording and the schema's required 'id' parameter make the context clear.

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