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

Annotations already declare readOnly, idempotent, closed-world, so the safety profile is fully covered. The description adds value by disclosing what each entry contains (who it's for, how it works, how it's billed, a link), though much of that is also captured by the 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?

One front-loaded sentence that puts the resource first and the per-item payload last. The dash-list is dense but every item earns its place by defining catalog scope.

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 no parameters and an output schema present, the description only needs to set expectations about content, which it does well. A small gap remains: nothing tells the agent how this catalog relates to the specific lookup siblings.

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 tool takes zero parameters, so there is nothing to disambiguate; baseline for a no-param tool 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?

Names the specific resource — Remoto's interpreting services — and enumerates the concrete service categories (video/audio, OPI, scheduled, sign language, RSI, portal, API, pro bono), which makes the scope unmistakable. It does not contrast itself with any sibling, but the catalog nature is clear from the enumeration.

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?

Usage is only implied: an agent can infer this is the browse/catalog entry point before picking a specific sibling like get_price_quote or find_interpreters, but the description never says so. No exclusions or pointers to alternatives are given.

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