get_training_readiness

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only restates the metric and date format, without explaining what happens when day is null, what the output shape is, or whether this is purely a read operation.

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 a single terse phrase with no filler or repetition, and the date format is front-loaded. It is appropriately concise for a simple getter, though it reads more like a label than a complete sentence.

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?

For a single-optional-parameter read tool, the description conveys the essential metric and date format, which may be enough for basic invocation. But with no annotations and no output schema, the lack of return-value details and default-behavior information keeps it at a minimally viable level.

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 gives zero description coverage, so the description adds meaningful value by specifying the expected YYYY-MM-DD format for day. However, it does not explain the meaning of null or the default value, leaving an important part of the parameter semantics undocumented.

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 identifies the specific metric (Morning Training Readiness) and clearly scopes it to a day with a YYYY-MM-DD format. It reads as a noun phrase rather than a full verb statement, and it does not distinguish this tool from the sibling get_morning_readiness, which appears to overlap in purpose.

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?

There is no explicit when-to-use guidance, exclusions, or mention of alternatives. The only implied usage context is that this tool provides readiness for a single day, which is thin but understandable given the simple one-parameter interface.

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