take_fx_get_name

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

Annotations already declare readOnlyHint=true, so the safe-read profile is covered. Beyond that the description adds nothing: no mention of what happens with an out-of-range fx_index, whether indices are zero-based, or what is returned on an empty FX chain. Only the bare 'get' semantics come from the text.

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 single sentence is short, but it ends with a dangling 'Args:' fragment that is a template artifact rather than content, which hurts rather than helps structure. Shortness here reflects missing information, not efficient packing.

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?

For a tool requiring four positional indices and providing no output schema, the description should at minimum explain the index chain (track→item→take→fx) and the return value. It does neither, so an agent cannot confidently construct a call.

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 0% and the description supplies no parameter information at all — the trailing 'Args:' is an unfilled placeholder. All four required indices (track_index, item_index, take_index, fx_index) are undocumented in both the schema and the description, leaving indexing conventions completely opaque.

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 and resource: 'Get the name of an FX plugin on a take.' The phrase 'on a take' implicitly separates it from the track-level sibling track_fx_get_name, though that sibling is never named. Purpose is unambiguous but not explicitly differentiated from alternatives.

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 take_fx_get_list, take_fx_get_param_name, or track_fx_get_name, nor any prerequisite such as needing a valid take with at least one FX. The usage context is only inferable from the name.

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