set_fx_send_fader

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

No annotations provided, so description carries full burden. It discloses that the operation sets a level in dB and slot range, but omits behavioral details such as whether the operation is reversible, required permissions, error behavior for out-of-range values, or side effects.

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?

A single sentence with 12 words, highly concise and front-loaded with essential information. No extraneous content.

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 tool has 2 required parameters and an output schema. The description covers the slot range but lacks details on level_db constraints and does not mention the output schema or any side effects. Adequate but not comprehensive.

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 has no descriptions for parameters (0% coverage). The description adds the slot range (1-4) for fx_slot but provides no information on level_db beyond 'dB'. Parameter semantics are partially improved but incomplete.

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?

Description clearly states the action ('set'), the resource ('FX send fader level'), the unit ('dB'), and the valid range ('slot 1-4'). It distinguishes from sibling tools like set_channel_fader and set_bus_fader.

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?

No guidance provided on when to use this tool versus alternatives, nor any prerequisites or context. The description only states what it does, not usage conditions.

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