get_today_resilience_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 resilience data for today' and mentions the return type ('Dictionary containing resilience data for today'), but doesn't describe authentication needs, rate limits, error conditions, or whether this is a read-only operation. For a tool with zero annotation coverage, this is insufficient behavioral context.

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 with two brief sentences that state the purpose and return value. It's front-loaded with the core functionality, though the 'Returns:' section could be integrated more smoothly. There's minimal waste, but it could be slightly more polished.

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 should provide more complete context. It mentions the return type but doesn't explain the structure of the resilience data, what 'today' means (e.g., timezone, date range), or how this differs from sibling tools. For a data retrieval tool with no structured output documentation, this leaves significant gaps.

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 with 100% schema description coverage, so the schema already fully documents the lack of parameters. The description doesn't add parameter information (which isn't needed here), maintaining the baseline of 4 for zero-parameter tools as per the guidelines.

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 'Get resilience data for today' which provides a clear verb ('Get') and resource ('resilience data for today'), but it doesn't distinguish this tool from its sibling 'get_resilience_data' (which presumably gets resilience data for other time periods). The purpose is understandable but lacks sibling differentiation.

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 like 'get_resilience_data' or 'get_today_readiness_data'. There's no mention of prerequisites, exclusions, or comparative context with sibling tools, leaving the agent to infer usage patterns.

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