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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds genuinely new behavioral context: the record returned is 'current' and the call deliberately does not validate offerings or availability, which warns the agent about potentially stale or unverified data.

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, no filler. The action and its input source come first, and the scope caveat is placed last rather than burying the primary instruction.

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 format need not be described, and annotations carry the safety profile. The description covers action, input origin, and a scope limitation, leaving only minor gaps such as behavior on a stale or unknown UUID.

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%, so the schema only gives type/format/pattern with no prose. The description compensates by stating the parameter's provenance ('a UUID returned by search_providers'), which is the key thing an agent needs to supply a valid value; it stops short of naming the field or noting failure behavior for unknown IDs.

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 and resource (get the current provider record) and anchors it to the sibling tool that produces the required identifier (search_providers). This lets an agent distinguish it from search_providers and open_provider_explorer without opening any schema.

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?

'using a UUID returned by search_providers' gives an explicit prerequisite and routing rule, and the closing sentence bounds what the tool is not for (it does not verify offerings or availability). No direct comparison against open_provider_explorer or list_regions, so it falls short of a full when/when-not map.

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