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

With no annotations provided, the description bears full responsibility for behavioral disclosure. It explains that talea and color cycles repeat independently, causing phasing, and that the full cycle length is the LCM of lengths. It also mentions return values (notes, lengths, duration). However, it does not mention potential side effects like overwriting existing notes or prerequisites (e.g., existence of a note track).

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 well-structured, starting with a definition, then historical context, then parameter details, then return values. It is slightly long but every paragraph adds value. Could be trimmed slightly, but no word is wasted.

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 moderate complexity (7 parameters, 0 required) and the presence of an output schema, the description provides comprehensive context: conceptual explanation, parameter formats, behavioral phasing, and return summary. It fully equips 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?

The description adds substantial meaning to all parameters beyond the input schema. For talea and color, it explains the comma-separated format and gives examples. Repeats, velocity, unit_index, track_index, and start_beat are all described with context. This fully compensates for the 0% schema description coverage.

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 creates an isorhythm, defines it as a repeating rhythm (talea) combined with a repeating pitch series (color), and distinguishes it from ostinato. The verb 'create' and specific resource 'isorhythm' are unambiguous. Historical context and contrast to ostinato further clarify its unique purpose among many sibling tools.

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 explains when to use an isorhythm (for medieval motets and 20th-century composers) and contrasts it with ostinato. However, it does not explicitly state when NOT to use it or list alternative tools for similar patterns. The guidance is clear but lacks explicit exclusion criteria.

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