setup_fx_chain

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

With no annotations, the description partially discloses behavioral traits through parameter modes (add, configure, find_or_add) but does not explicitly state whether the tool is destructive (e.g., overwrites existing FX), requires permissions, or has side effects. It focuses on parameter details rather than overall tool behavior.

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 front-loaded with a clear first sentence and organized into an Args section. While slightly lengthy, every part adds value, and the structure aids readability. Could be slightly more concise but not wasteful.

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 description provides comprehensive parameter guidance but lacks information about return values (e.g., success/error handling) and does not mention any post-conditions or error cases. Given the tool's complexity and lack of output schema, these gaps reduce completeness.

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 0%, so the description fully compensates by providing a detailed breakdown of the 'tracks' JSON structure, including track_index, fx_chain with name, params, preset, fx_index, add_mode, and value ranges. This adds significant meaning beyond the schema's minimal 'type: string' definition.

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 the tool performs batch addition/configuration of FX across tracks, which is a specific verb-resource pair. It distinguishes itself from sibling tools like fx_add and fx_set_param by noting it replaces many individual calls, making its purpose unambiguous.

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 implies usage for batch operations where multiple fx_add and fx_set_param calls would otherwise be needed, providing context. However, it lacks explicit guidance on when not to use this tool (e.g., for single FX operations) or alternative tools beyond fx_add and fx_set_param.

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