get_service

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds nothing beyond that — no note on what happens when the id does not exist, or whether the id refers to a service record vs. a flow/etc. For an annotated tool this is minimal added value.

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?

It is short and front-loaded, but the second sentence is redundant with the first and the brevity stems from under-specification rather than tight editing. One sentence could have carried the same plus more.

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 single-parameter read tool with rich annotations and no output schema, little is strictly required. Still, the description says nothing about what a 'service' is in this domain or what the response contains, leaving the agent to guess relative to siblings like get_faq or get_flow.

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 coverage is 100% and the single parameter 'id' is documented as a numeric id. The description's "by id" adds no format, source, or lookup semantics (e.g., how to obtain a valid id, whether it comes from list_services). Baseline 3 applies when the schema carries the load.

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 verb and resource are named ("Get a service"), which is more than a bare restatement of the name, but the second sentence ("One service by id.") only rephrases the first. Nothing distinguishes it from siblings like list_services or get_faq, so an agent gets the gist but no differentiation.

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 mention of list_services for enumeration vs. single retrieval, and no prerequisites or error conditions. The agent must infer usage purely from the name.

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