wait_beats

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

With no annotations, the description carries full burden but only states it 'waits,' without detailing blocking behavior, accuracy, or side effects. While adequate for a simple tool, more transparency (e.g., whether it blocks execution) would improve score.

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 extremely concise: two sentences plus a two-line parameter list. Every sentence adds value with no redundancy, and the purpose is front-loaded.

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?

Given the tool's simplicity, the description is sufficiently complete. It covers the core behavior and parameters. The presence of an output schema reduces the need to describe return values. Minor room for improvement includes clarifying output or edge cases.

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 description adds meaning beyond the schema by explicitly naming and explaining each parameter: 'beats: Number of beats to wait' and 'bpm: Current tempo (default 95).' This compensates for the zero schema description coverage, providing clear semantics.

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 waits for a specified number of beats, distinguishing itself from related tools like get_tempo or set_tempo. The verb 'wait' and resource 'beats' are specific and unambiguous.

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 mentions it is 'useful for timing operations in a sequence of MCP tool calls,' providing context for when to use it. However, it lacks guidance on when not to use it or explicit alternatives, though the context from sibling tools implies its specific purpose.

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