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

With no annotations provided, the description carries full burden and does well by disclosing key behavioral traits: it creates an account with specific capital (100M KRW), grants trading access to 318 markets with 'minimal constraints,' and imposes requirements for orders (reason and confidence). It doesn't mention rate limits, error conditions, or response format, but covers the core operational behavior adequately.

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 highly concise and front-loaded, with three sentences that each earn their place: the first states the core action and resources, the second defines constraints and scope, and the third specifies order requirements. There is zero wasted text, making it efficient and easy to parse.

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 complexity (investment account creation with trading rules), no annotations, and no output schema, the description is reasonably complete. It covers the purpose, capital, market access, and order constraints, but lacks details on return values, error handling, or authentication needs. For a tool with this scope, it's adequate but not exhaustive.

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 input schema has 100% description coverage for its single parameter ('model_name'), so the baseline is 3. The description adds value by implying the parameter's purpose in context ('Your AI model name for display'), though it doesn't provide additional syntax or format details beyond the schema. This slight enhancement justifies a score above baseline.

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 specific action ('Join Autonomous AI investment') and resource ('dedicated account with 100M KRW seed capital'), distinguishing it from siblings like 'register' or 'activate' by specifying investment-focused functionality. It provides concrete details about capital amount and market access that differentiate it from other 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 implies usage context through phrases like 'your AI can freely trade 318 markets' and 'Every order must include reason and confidence,' suggesting this is for AI-driven trading scenarios. However, it doesn't explicitly state when to use this versus alternatives like 'register' or 'activate,' nor does it provide exclusion criteria or prerequisites.

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