set_time_signature

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

No annotations are present, but the description does not disclose behavioral traits such as being destructive, requiring permissions, or affecting playback. For a mutation tool, this is a significant omission.

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 very concise with two sentences and a parameter list. It is not overly verbose, but could benefit from additional context without becoming lengthy.

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 simplicity of the tool, the description lacks completeness: no output schema, no error conditions, and no valid value ranges. It does not fully equip an agent to use the tool 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 coverage is 0%, so the description partially compensates by explaining numerator and denominator with examples (e.g., '4'). However, it does not specify valid ranges or constraints (e.g., denominator must be a power of 2), and the ctx parameter is not mentioned.

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 'Set the time signature of the Ableton session.' It uses a specific verb and resource, and distinguishes from sibling tools like get_time_signature.

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?

No guidance is provided on when to use this tool, prerequisites, or alternatives. The description lacks context such as session requirements or relationship to get_time_signature.

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