get_queue_snapshot

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

With no annotations, the description carries the behavioral burden. It does disclose a key trait: 'Read-only', which informs the agent that no mutation occurs. However, it does not mention how 'full' interacts with the max_results parameter, whether the response format affects what is returned, or any error/auth/rate-limit behavior. The disclosure is minimal but not misleading.

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 a single, tight sentence that front-loads the core purpose, enumerates the returned data, and appends the safety note. There is no filler or redundant restatement.

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 description covers the essential return content and read-only nature, but it omits important context: how max_results affects the 'full' queue promise, what response_format values mean in practice, and why an agent should prefer this over get_queue. Given no output schema and no annotations, a bit more context would materially improve call correctness.

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 100%, so the schema fully documents max_results and response_format. The description adds no parameter-level meaning beyond the schema, which is the expected baseline. It neither clarifies defaults nor adds examples.

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 a specific verb ('Return'), a clear resource ('full upcoming queue'), and the key computed values (per-track runtime and total queue runtime). It is unambiguous about what the tool produces, but it does not explicitly distinguish itself from the sibling 'get_queue' or 'queue_runtime_report'.

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 description gives no guidance on when to use this tool versus alternatives like 'get_queue' or 'queue_runtime_report'. 'Read-only' is a safety signal, not a usage condition. An agent must infer when the extra runtime details justify this tool over simpler queue tools.

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