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

With no annotations provided, the description carries the full disclosure burden. It reveals the operation generates an API key and retrieves deposit info (side effects/outputs), and the 'No auth needed' disclosure is crucial behavioral context. However, it omits error handling (e.g., duplicate email), idempotency, or rate limit details expected for an account creation tool.

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?

Two sentences, zero waste. Front-loaded with the primary action (account creation), followed by secondary outputs (API key, deposit info), and closes with the critical constraint (no auth needed). Every clause earns its place.

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 no output schema, the description partially compensates by disclosing that the operation returns/generates an API key and deposit info. With 100% schema coverage and simple parameter structure, this is sufficient context, though error scenarios remain undocumented.

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%, establishing baseline 3. The description implies email/password are for the new account but does not add parameter-specific semantics beyond the schema (e.g., password requirements, email validation rules) or explain the parameter relationship to the generated API key.

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?

Description uses specific verb 'Create' with resource 'Merx account' and distinguishes from siblings like 'login' (existing auth) and 'set_api_key' (configuring existing credentials). The additional clauses about generating an API key and getting deposit info clarify the full scope of the operation.

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 'No auth needed' clause provides critical contextual guidance distinguishing this from most sibling tools that likely require authentication. However, it lacks explicit guidance on when to use this versus 'login' (e.g., 'for new users only').

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