load_midi_file

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool loads and parses a file, implying a read operation, but doesn't cover aspects like error handling (e.g., what happens if the file is invalid or missing), performance considerations, or output format. This leaves significant gaps for a tool that interacts with file systems.

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 a single, efficient sentence that directly states the tool's function without unnecessary words. It is front-loaded with the core action and resource, making it easy to understand at a glance.

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?

Given the lack of annotations and output schema, the description is incomplete for a file-loading tool. It doesn't explain what the parsed output entails (e.g., structured data or events), error scenarios, or how it integrates with sibling tools, leaving the agent with insufficient context for effective use.

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?

The schema description coverage is 100%, with the single parameter 'filePath' fully documented in the schema. The description adds no additional meaning beyond what the schema provides, such as file format specifics or path requirements, so it meets the baseline for high schema coverage without compensating value.

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 action ('Load and parse') and resource ('a MIDI SMF file from the specified path'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_midi_events' or 'get_midi_summary' which might also involve loading MIDI files, so it doesn't reach the highest clarity level.

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 provides no guidance on when to use this tool versus alternatives like the sibling tools listed. It doesn't mention prerequisites, such as needing a valid file path, or specify use cases like initial file loading before accessing events or summaries.

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