get_metasound_preset_parameters

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so the safety profile is covered. The description's implementation narrative (loads preset, obtains builder, iterates GetGraphInputNames) adds little behavioral value beyond confirming it is a plain read; it doesn't note any failure modes for a bad/missing preset path.

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?

Front-loads the purpose, then a brief implementation note, then the return shape. Two sentences, no filler. The internal iteration detail is slightly more than needed but not wasteful enough to pull it below 4.

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?

No output schema exists, and the description compensates by spelling out the return object (preset_path, parameters[{name,type,value}], parameter_count), which is exactly what the agent needs. For a single-param read tool with full annotation coverage, this is nearly complete.

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?

Only one parameter with 100% schema description coverage, so the schema already documents preset_path as the content path. The description reiterates preset_path only via the return object and adds no new parameter meaning. Baseline 3 applies.

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?

Specific verb+resource: 'Gets all parameter defaults from a MetaSound preset.' Clearly distinguished from write siblings like set_metasound_preset_parameter by reading defaults rather than setting values. Does not explicitly name a sibling alternative, so it stops short of a 5.

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?

Usage is only implied by the name and description ('Gets all parameter defaults'). There is no explicit when-to-use guidance, no prerequisites, and no routing to alternatives such as get_metasound_graph_info or get_metasound_node_info which also surface MetaSound info.

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