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

Annotations already declare readOnlyHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds only the raw HTTP path, which is structural rather than behavioral — nothing about error/404 behavior, permissions, or whether the location record includes nested relations.

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 with zero filler, and the core operation is front-loaded. Slightly under-specified for its length rather than padded.

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 read tool with full schema coverage and read-only annotations, the description is just barely sufficient to invoke correctly. With no output schema, it would benefit from a sentence on what a location record contains, but that omission doesn't block invocation.

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 location_id parameter is fully documented with type and bounds, so the baseline is 3. The description's "by id" restates the schema rather than adding format, sourcing, or lookup-hint value.

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?

"One location by id" states the resource and cardinality precisely, and the REST path disambiguates it as a single-record fetch rather than a search. It doesn't name fieldpulse_list_locations as the alternative, but the singular noun makes the distinction inferable.

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 call this versus fieldpulse_list_locations, no prerequisites, and no mention of what happens when the id is unknown. The agent must infer the routing entirely from the tool name.

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