Get channel state

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

Annotations already declare readOnlyHint and idempotentHint, so the description does not need to repeat those. It adds value by listing the returned properties, but does not disclose any further behavioral traits (e.g., no channels case, permissions, rate limits).

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 concise sentence that immediately conveys the tool's purpose. It is efficiently front-loaded with 'All' and leaves no unnecessary words.

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?

Given the presence of an output schema and the simple nature of the tool (get all state), the description is sufficiently complete. It lists the fields returned, and the annotations indicate read-only and idempotent behavior, covering most contextual needs.

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?

With no parameters, the description correctly focuses on the output. The baseline for 0 parameters is 4, and the description adds meaning by enumerating the properties included in the result, which helps the agent interpret the return value.

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 clearly states it returns all channel-rack channels with specific properties (index, name, volume, pan, mute, solo). It uses a specific verb+resource and distinguishes from sibling tools like fl_set_channel_* (write operations) and fl_get_channel_routing (different resource).

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 provides no explicit guidance on when to use this tool versus alternatives. It does not mention when not to use it or suggest other tools for different purposes, such as writing parameters or getting routing information.

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