get_today_readiness_data

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. It states the tool 'Get[s] readiness data for today' and describes the return format ('Dictionary containing readiness data for today'), but lacks critical details like whether this requires authentication, has rate limits, or what specific data fields are included. For a 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 concise and well-structured: a clear purpose statement followed by a brief return format. Both sentences are necessary and front-loaded. However, it could be slightly more efficient by integrating the return format into the main sentence (e.g., 'Get readiness data for today, returning a dictionary.').

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 lack of annotations and output schema, the description is incomplete. It doesn't explain what 'readiness data' entails (e.g., metrics, timestamps), how the data is structured in the dictionary, or any behavioral constraints. For a data retrieval tool with no structured support, more context is needed to be fully helpful.

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 tool has 0 parameters, and the input schema has 100% description coverage (though empty). The description doesn't need to add parameter semantics, so it meets the baseline for tools with no parameters. It appropriately focuses on the tool's function rather than inputs.

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: 'Get readiness data for today.' It specifies the verb ('Get') and resource ('readiness data') with temporal scope ('for today'). However, it doesn't explicitly differentiate from sibling tools like 'get_readiness_data' (which might have different temporal parameters), so it doesn't reach the highest score.

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. It doesn't mention sibling tools like 'get_readiness_data' (which might retrieve data for other time periods) or 'get_today_resilience_data' (which fetches a different type of data for today). There's no context on prerequisites or exclusions.

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