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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is fully covered. The description adds only the return content hint (stops/items + info cards), which is modest value beyond the structured fields and the existing output schema.

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 telegraphic fragments with zero waste, front-loading the resource and its payload. It is efficient, though the clipped style trades some readability for brevity.

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?

With an output schema present, return values need not be explained, and annotations carry the safety profile, so the description is nearly complete. The remaining gap is routing guidance among the dense set of get_/list_ siblings (program vs template vs trip).

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 0%, but there is only one parameter and the schema itself declares type string, format uuid, and a strict pattern. The description's 'Params: id (uuid)' merely restates the schema without adding selection meaning, so a baseline 3 is appropriate.

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+resource: retrieving details of a single travel program, and enumerates what it returns (stops/items + info cards). The singular framing implicitly distinguishes it from list_my_programs, but no sibling is named, so differentiation is left to inference.

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 when-to-use guidance and no alternatives named. It does not tell the agent to reach for list_my_programs to enumerate or get_my_template/get_my_trip for the analogous resources, so routing is entirely implied by the singular name.

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