midi_to_reaper

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

With no annotations at all, the description carries the full behavioral burden, yet it omits prerequisites (is Reaper required to be running/connected?), whether the import is additive or overwrites an existing track, and any permissions or failure behavior. The 'for:' bullets describe downstream outcomes rather than how the tool behaves, which is the weaker form of disclosure.

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 action sentence is front-loaded and the whole definition is short. The trailing bullets are somewhat padded — 'mixing and mastering' is a vague outcome for an import operation — but overall it is tight and scannable.

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 two-parameter tool with full schema coverage and an output schema, the description covers the minimum: what it does and what the import enables. It still leaves out the operational context an agent needs (Reaper availability, result expectations), which keeps it at adequate rather than 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?

Schema description coverage is 100%, with both midi_file and track_name documented (including a default), so the schema does the heavy lifting. The description adds nothing about path format, acceptable MIDI variants, or defaulting behavior, so the 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?

The description states a specific verb and resource ('Import a MIDI file into Reaper DAW'), so the core action is unambiguous. It does not, however, differentiate itself from close siblings like play_midi_file, record_midi_performance, or send_midi_note, leaving the agent to infer the boundary.

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 bullet list implies when the tool is useful (rendering with virtual instruments, editing/arrangement, mixing), which is contextual intent rather than explicit routing guidance. It never says when NOT to use it or why it beats play_midi_file for a given task, so the guidance remains implied.

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