load_item_to_track

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

With no annotations, the description carries the full burden for behavioral disclosure. It states that the tool loads an item but does not describe side effects such as whether the item replaces existing devices, whether it is appended, any permissions needed, or what happens on failure. This is a gap for a mutating operation.

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 concise and well-structured. The opening sentence states the purpose, followed by a bulleted list of parameters. Every sentence earns its place, with no redundant or extraneous information.

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 covers the essential purpose and both parameters, but lacks behavioral context such as return value, error conditions, or effects on the track's existing devices. Given the absence of an output schema and annotations, some additional context would be expected for a complete picture.

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%, so the description must compensate. It provides inline parameter explanations: track_index is 'the index of the track to load the item onto' and uri is 'the URI of the browser item (obtained from browse_path or search_browser).' This adds meaning beyond the bare schema titles, though it does not specify zero-based indexing or format details.

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's function: 'Load a browser item (instrument or effect) onto a track by URI.' This uses a specific verb ('load'), identifies the resource (browser item), and indicates the target (track). It also differentiates from siblings like load_item_to_return by explicitly saying 'onto a track.'

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 by specifying the URI source ('obtained from browse_path or search_browser') and the target ('onto a track'). However, it does not explicitly state when to use this tool over alternatives like load_item_to_return or load_instrument_or_effect, nor does it mention any exclusions or prerequisites.

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