get_overview

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

With no annotations, the description carries the full burden, and it does disclose a meaningful side effect: conditional incremental synchronization driven by coverage status. It does not explain whether this is read-only, what sync failures look like, or the trigger conditions beyond '必要时' (when necessary).

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 front-loaded sentence that lists the overview contents before the optional sync behavior. There is no filler or repetition.

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?

An output schema exists, so return-value explanation is not required, and the description covers the major dashboard domains plus sync behavior. It still leaves a key gap for a multi-domain overview: it does not define the time window semantics of '近期' (recent) or connect the two date parameters to the displayed data.

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%, and the description never mentions 'days' or 'end_date'. It does not clarify whether the period applies to training, load, recovery, or the next-race lookup, leaving the schema's typed fields to speak for themselves.

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 a specific verb ('查看' / view) and enumerates the resource components: recent training, unified load, recovery, and next race. This makes it distinguishable from single-domain siblings like get_training_load or get_recovery_status, though it does not explicitly frame itself as an aggregate of those tools.

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?

It implies usage as a one-page overview and notes that incremental sync happens 'when necessary based on coverage status,' which gives some context. However, it does not say when to choose this tool over query_activities, get_training_load, get_recovery_status, or sync_now.

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