generate_chord_progression

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

No annotations exist, and the description does not disclose behavioral traits beyond parameter names. It states it returns a chord progression but omits side effects, permissions, or constraints (e.g., whether it modifies the 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 well-structured with Args and Returns sections, front-loading the core purpose. It is relatively concise but could be slightly more terse (e.g., removing repeated 'Default' info already in schema).

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 (4 optional parameters, output schema exists), the description covers all key aspects: purpose, parameters, and return type. It lacks validation details but is largely complete for a generative tool.

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?

With 0% schema description coverage, the description provides meaningful parameter details (e.g., key examples, default length, style options, ending types). This adds value beyond the schema, which only has defaults and types.

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 'Generate a chord progression' and lists relevant parameters (key, length, style, ending). It effectively conveys the main purpose, though it does not explicitly distinguish from siblings like suggest_next_chord.

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 versus alternatives (e.g., suggest_next_chord) or when not to use it. The description only explains what the tool does.

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