capture_track_state_snapshot

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral context: the result is a consistent, persistable JSON snapshot, not a native track preset, and it intentionally omits certain state categories. No contradiction with annotations.

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 two sentences with no filler. The primary action and output type are front-loaded, and the second sentence efficiently lists exclusions. Every clause earns its place.

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 single-parameter, read-only capture tool with annotations covering safety, the description adequately states what is captured, what is excluded, and that the output is a persistable JSON snapshot. It does not detail the exact JSON shape or how to later restore the snapshot, but this is not critical given the schema and the simple read-only nature of the tool.

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 trackId documented as 'Stable track ID returned by list_tracks.' The description's phrase 'existing track' adds slight emphasis on validity, but it does not meaningfully extend the parameter semantics beyond what the schema already provides. Baseline 3 is appropriate.

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 uses a specific verb ('Capture') and precisely defines the resource: 'one consistent, persistable JSON snapshot of an existing track's mixer, routing, and exposed parameters for ordered top-level devices.' It also distinguishes itself from a native track preset and names exclusions, making it clear what the tool does and does not capture relative to siblings.

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 conveys a clear context for use: capturing a track-level snapshot of mixer, routing, and exposed top-level device parameters. It also provides explicit when-not guidance by excluding clips, nested devices, hidden state, samples, automation, and mappings, but it does not name a specific alternative tool to use for those excluded cases.

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