take_fx_get_num_params

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds nothing beyond that: no note on indexing conventions, error behavior for invalid indices, or what happens when the take has no FX.

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 core sentence is short and front-loaded, but the trailing dangling 'Args:' is leftover template scaffolding that provides no information and indicates an incomplete definition.

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?

With no output schema, no parameter documentation, and no behavioral notes, the description leaves the agent unable to call this four-required-parameter tool confidently. It should at minimum explain the index semantics and the integer return value.

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?

All four parameters (track_index, item_index, take_index, fx_index) have 0% schema description coverage, and the description supplies no meaning for any of them. It is unclear whether indices are 0-based, 1-based, or what an 'item_index' resolves to.

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 plus resource: get the number of parameters for an FX plugin on a take. It implicitly distinguishes this take-level tool from the sibling track_fx_get_num_params, though it never names that sibling explicitly.

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 versus track_fx_get_num_params, take_fx_get_param, or take_fx_get_param_name. The agent must infer usage from the name alone, and no prerequisites or context are given.

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