generate_pattern

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. While 'generate' implies creation, it doesn't specify what 'complete pattern' means in terms of output format, whether it's a one-time generation or iterative, what happens with the generated pattern (saved, played, returned), or any constraints like computational requirements. For a generation tool with zero annotation coverage, this is insufficient.

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 at just 4 words ('Generate complete pattern from style'), with no wasted words. It's front-loaded with the core action and resource. Every word earns its place by establishing the tool's fundamental purpose efficiently.

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 complexity of pattern generation, no annotations, no output schema, and many similar sibling tools, the description is incomplete. It doesn't explain what constitutes a 'complete pattern', how the output is structured or returned, or how this differs from other generation tools. For a creative generation tool in a crowded namespace, more context is needed.

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 100%, so the schema already documents all three parameters (style, key, bpm) with clear descriptions. The description mentions 'style' but doesn't add any semantic context beyond what the schema provides about how these parameters influence pattern generation. With high schema coverage, the baseline score of 3 is appropriate.

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's purpose as 'Generate complete pattern from style', specifying the verb 'generate' and the resource 'complete pattern'. It distinguishes from siblings like 'generate_bassline' or 'generate_drums' by indicating it creates a full pattern rather than specific components. However, it doesn't explicitly contrast with 'ai_generate_pattern' or other pattern-related 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 provides no guidance on when to use this tool versus alternatives. With many sibling tools like 'generate_bassline', 'generate_drums', 'ai_generate_pattern', and 'get_pattern', there's no indication of when this specific pattern generation tool is appropriate versus those other options. The description simply states what it does without context.

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