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

Annotations indicate readOnlyHint and openWorldHint, which are consistent with the description's claim of returning a deliverable. The description adds that inputs are validated server-side, but no additional behavioral context (e.g., cost, latency, data sources) beyond annotations.

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 short and front-loaded with the purpose. The reference case adds some context but could be considered extraneous. Overall efficient.

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 the inputs (5 parameters, deep nesting) and lack of output schema, the description does not provide enough context on what the deliverable contains or how to interpret results. An agent would lack understanding of the tool's output and return structure.

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 only 20%, and the description does not explain any parameter meanings beyond 'send the documented case fields.' The complex nested inputs (company, growthTarget, etc.) are left to the schema alone, which is insufficient for an agent to know how to fill them properly.

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 is for growth architecture, targeting C-suite expertise, and returns a structured deliverable. It gives a reference case (Pennylane). However, it does not differentiate from many similar strategy planning siblings.

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 explicit guidance on when to use this tool vs alternatives. The description only says to send documented case fields, but does not indicate prerequisites, when not to use, or comparison to siblings like market_entry_strategist or strategic_options_analyzer.

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