get_morning_training_readiness

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

Annotations only cover readOnlyHint and openWorldHint; the description goes further by disclosing that there is no HTTP call of its own, that it delegates to getTrainingReadiness, that it filters on inputContext and falls back to the first entry, and that it returns null for a falsy/empty result. That edge-case behavior (fallback and null) is exactly the kind of trait annotations cannot express.

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?

A single dense sentence with no filler, front-loaded on the delegation behavior. It is efficient, though the semicolon-chained internal details read more like implementation notes than a crisp summary.

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 one-parameter read tool with annotations present, the description covers delegation, filtering, fallback, and the null case. It stops short of describing what the returned readiness object contains, which matters somewhat since there is no output schema to carry that burden.

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 100% and the single cdate parameter is fully documented in the schema as YYYY-MM-DD UTC, so the description is not required to compensate. It adds nothing about cdate, which is fine given the schema does the heavy lifting.

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 reveals that it wraps getTrainingReadiness and applies an AFTER_WAKEUP_RESET filter, which implicitly conveys the purpose (morning readiness snapshot). However, it is framed as implementation notes rather than a user-facing statement of what is returned, and it never explicitly contrasts itself with the sibling get_training_readiness.

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 or routing to alternatives. The filter condition (AFTER_WAKEUP_RESET) hints at when this differs from get_training_readiness, but the agent is left to infer that this is the 'morning' variant rather than being told to prefer it in that scenario.

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