get_midi_capture_context

Read-onlyIdempotent

Get MIDI capture readiness, armed tracks, playing-clip risks, input routing, and clip timing to plan recordings without exposing buffer contents.

Instructions

Read global Capture MIDI readiness, armed/monitored candidates, playing-clip risks, input routing, full-note digests and clip timing with native identity. Does not expose buffer contents or reserve a moving playhead.

  2. Addedv0.3.0

TDQS

A3.8/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful behavioral boundaries by stating that it does not expose buffer contents or reserve a moving playhead, which helps set expectations beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two front-loaded sentences that are dense but purposeful: the first lists the context returned, and the second states key limitations. There is no redundant restatement of the tool name or annotations.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no parameters, rich read-only annotations, and an output schema present, the description provides enough context for correct invocation. It names the main areas of returned context and clarifies what is deliberately excluded, while the output schema can carry return-value details.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so there is no parameter semantics to document. The baseline for a zero-parameter tool is 4, and the description appropriately does not invent parameter details.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb, 'Read', and names the resource and scope: global Capture MIDI readiness, armed/monitored candidates, playing-clip risks, input routing, and clip timing. It is clearly a read-only context getter, but it does not explicitly distinguish itself from siblings such as capture_midi_session or get_transport_recording_context.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies that the tool is used to inspect MIDI capture readiness, but it gives no explicit guidance on when to use it versus related siblings like capture_midi_session or get_transport_recording_context. The second sentence states limitations, not selection criteria or alternatives.

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