get_control_bus_mix_info

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered; the description reinforces this with 'without changing it'. It adds genuinely useful behavioral detail beyond the annotations, notably the edge case that bus_path is empty when the bus reference is cleared.

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?

Front-loads the purpose and then the return detail, which is the right order. It is slightly redundant: the stage fields are enumerated in prose and then restated verbatim as a JSON shape, which duplicates rather than adds.

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?

Since there is no output schema, the description carries the return-shape burden and discharges it by listing mix_path, stage_count and per-stage fields including the cleared-bus edge case. Missing only pagination/size expectations, but for a single-asset read it is essentially complete.

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 coverage is 100% and the single parameter mix_path is already documented as the asset path to the USoundControlBusMix. The description mentions mix_path only as part of the return payload, adding no new syntax or format guidance, so the baseline 3 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?

States a specific verb ('Reads') and resource ('the stages of a USoundControlBusMix asset') with explicit scope ('without changing it'), and names the sibling set_control_bus_mix_stage_value that handles the mutating counterpart. An agent can distinguish it from that sibling without opening either 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?

It names the alternative explicitly ('Edit a stage with set_control_bus_mix_stage_value'), which routes the agent between read and edit. However it gives no explicit when-to-use context (e.g. after what workflow you'd inspect a mix) or prerequisites, so it is clear context without full exclusions.

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