training_readiness

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

With no annotations provided, the description carries the full burden. It does not disclose any behavioral traits: whether it is read-only, requires authentication, has rate limits, or what the output represents. The description only restates the concept of readiness without 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 extremely short (one sentence), but it is under-specified rather than efficiently informative. It lacks substance, so brevity is not a virtue here.

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?

Despite having an output schema, the description fails to provide essential context. It does not explain what the tool returns, how the readiness score is computed, or how the optional date parameter affects results. The description is completely inadequate for an agent to correctly select and invoke the tool.

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 0%, so the description must compensate for the single 'date' parameter. It does not mention the parameter at all, leaving the agent without any guidance on format, meaning, or usage (e.g., date format, default behavior).

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 '训练准备度 — 当日身体准备训练的程度' (training readiness - degree of readiness for the day), but it lacks a verb to indicate what the tool does (e.g., 'retrieves', 'provides'). It is nearly tautological with the name, and does not distinguish it from sibling tools like 'training_status' which likely 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?

No guidance is provided on when to use this tool versus alternatives. The description gives no context about prerequisites, scenarios, or exclusions, leaving the agent to guess among many sibling tools.

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