list_media_subscriptions_template

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the HTTP method (GET) and parameter scoping, but does not disclose any additional behavioral traits such as response shape, error conditions, or rate limits. No contradictions with annotations.

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?

The description is highly concise, containing the endpoint and an 'Args' list with one-line definitions. No filler or repetition — every sentence earns its place.

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?

The output schema exists (so return values are documented) and annotations cover read-only/idempotent behavior. The description is adequate for a trivial GET endpoint, but it omits any context about what a 'template' is or when to use this endpoint versus sibling subscription endpoints, which is a meaningful gap in a large API surface.

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 description must compensate for missing parameter documentation. It provides a one-line explanation for each of the three parameters (guid, type, target_library_section_id), which gives an agent enough meaning to construct arguments, even though some explanations are terse ('Subscription type.').

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 states 'Get the subscription template' — a specific verb and resource. It is clear enough but does not explicitly differentiate from sibling subscription tools like list_media_subscriptions or get_media_subscriptions_by_subscription_id, so it misses the distinction criterion for a 5.

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 guidance on when to use this tool versus alternatives. The description simply presents the endpoint and arguments without mentioning scenarios, prerequisites, or exclusions. An agent must infer usage from the name alone.

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