create_demo_shop

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

With no annotations provided, the description carries full burden for behavioral disclosure. While it mentions executing a sequence of API calls and generating a 'live trace', it doesn't disclose important behavioral aspects: whether this creates persistent data, what authentication is required, whether it's idempotent, what side effects occur, or what the output format looks like. The description provides some context about the multi-step nature but misses critical operational details.

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 appropriately concise with two sentences that each serve a distinct purpose: the first explains what the tool does, the second explains when to use it. There's no redundant information or unnecessary elaboration. The structure could be slightly improved by front-loading the core functionality more clearly, but overall it's 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 this is a multi-step API execution tool with no annotations and no output schema, the description is insufficiently complete. It doesn't explain what the tool actually creates (despite the name 'create_demo_shop'), what the output looks like, what errors might occur, or important behavioral constraints. For a tool that presumably orchestrates multiple API calls with potential side effects, more comprehensive documentation 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?

The input schema has 100% description coverage, with the single parameter 'api_url' clearly documented as 'Optional URL to simulate the Tunzaa environment for grounding.' The description doesn't add any meaningful parameter semantics beyond what the schema already provides - it doesn't explain when to use the api_url parameter, what values are valid, or how it affects the execution. Baseline 3 is appropriate when schema coverage is complete.

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 states the tool 'executes a full sequence of Tunzaa API calls (Token -> Payment -> Installments)', which provides a clear high-level purpose. However, it doesn't specify what resource is being created (a 'demo shop' as implied by the name) or differentiate from sibling tools like 'initiate_payment' or 'get_token' that handle individual steps. The phrase 'ultimate grounding tool' is vague marketing language rather than functional specification.

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 explicitly states 'Use this to see a 'live trace' of the API, allowing you to generate perfect integration code', which provides clear context about when this tool should be used (for API exploration and code generation). However, it doesn't mention when NOT to use it or explicitly contrast with sibling tools that handle individual API steps, leaving some ambiguity about alternative approaches.

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