set_track_arm

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 explains the boolean arm parameter (True to arm, False to disarm) but does not mention any side effects, error conditions, or the indexing convention for track_index (e.g., zero-based vs. one-based), which is crucial in audio software. This is a significant gap.

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: a one-sentence purpose followed by a simple parameter list. No unnecessary words, and the key action is front-loaded. Every sentence 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 simple setter with two parameters and no output schema, the description covers the basic purpose and parameter meanings, but it lacks important context such as the indexing convention, track type constraints, or any behavioral notes. It is minimally viable but not rich enough to fully inform an agent without additional assumptions.

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 coverage is 0%, so the description must compensate. It does so by explicitly defining both parameters: track_index as 'the index of the track' and arm with its meaning. This adds clear semantics beyond the bare schema titles, though it could be richer (e.g., specifying index bounds).

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 purpose: 'Set the arm (record enable) state of a track.' It uses a specific verb ('set') and resource ('arm state of a track'), and distinguishes it from sibling tools like set_track_mute or set_track_solo by focusing on the unique arm action.

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 for arming or disarming a track for recording, but it does not provide explicit guidance on when to use this tool versus alternatives like unarm_all or set_track_volume. It lacks context about prerequisites or typical scenarios, making it merely adequate.

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