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

With no annotations provided, the description carries the full burden. It discloses a meaningful side effect: 'Default flags mute the previous clip on the track.' It does not explain flag variations or reversibility, but the primary mutation is transparent.

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?

Two sentences with no filler: the action is front-loaded, the prerequisite is stated briefly, and the default side effect is provided. 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?

The description covers the essential prerequisite and default behavior, but with no annotations, no output schema, and 0% parameter documentation, the missing semantics around flags and the exact roles of track/block leave noticeable gaps for an agent deciding how to call this correctly.

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 0%, so the description must compensate. It adds partial meaning by clarifying that 'track' is where the previous clip is muted and that 'flags' have a default mute behavior, but it does not explain what integer values represent or how 'block' maps to a clip.

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 identifies a specific action ('Trigger') and resource ('performance-mode live clip'), and adds a key scoping condition. It does not explicitly contrast with related sibling tools, but the operation is distinct enough among the sibling list.

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 states an explicit prerequisite: 'playlist must be in performance mode.' This gives the agent a concrete condition for when the tool is valid, though it does not mention alternatives or when not to use it.

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