subscriptions_subscription_availability_get_to_one_relationship

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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses nothing beyond the deprecation warning: no auth requirements, no indication of whether the availability object is included, no pagination or rate-limit context. The deprecation flag is the single piece of added behavioral information.

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, but the URL is duplicated verbatim inside parentheses with no added value, which is wasted space. Front-loading the deprecation notice is the one structural positive.

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?

No output schema and no annotations mean the description must carry more weight, yet it supplies only a deprecation warning with no migration pointer to the non-deprecated sibling. For a relationship-fetch tool the agent needs to know what happens to the id and where to go instead, both absent.

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?

There is one parameter with 100% schema description coverage ('the id of the requested resource'), so the schema already documents it fully. The description adds nothing about id semantics, which is acceptable at baseline when schema coverage is high.

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 description is essentially the raw URL path restated twice, with no plain-language verb-and-resource statement. An agent can infer it retrieves the subscriptionAvailability relationship for a subscription, but the description is a tautological restatement of the tool name rather than an explanation of purpose.

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?

The only guidance is the [DEPRECATED] tag, which usefully signals avoidance but does not name the replacement — despite subscriptions_subscription_availability_get_to_one_related existing as a clear sibling. No when-to-use or when-not-to-use context beyond the deprecation marker.

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