get_market_regime

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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description reinforces this with 'Read-only, live exchange APIs.' It adds useful behavioral context beyond the annotations: the verdict is composite of trend/ranging and cross-venue funding rate, and the output includes confidence and a strategy hint. It does not cover rate limits or failure modes, but with annotations present the safety profile is sufficiently disclosed.

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 two sentences and front-loads the key deliverable: the market regime values, confidence, and strategy hint. The verification sentence is dense but not bloated, and there is no redundant padding.

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 read-only retrieval tool with three well-documented parameters and no output schema, the description supplies the return values, confidence, strategy hint, and composite methodology. It lacks explicit sibling routing and exact response structure, but those gaps are minor given the schema enum coverage and annotations.

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%, so the baseline is 3. The description adds little about the exact parameters beyond limiting the tool to a single crypto perpetual futures asset. It does not add syntax, default semantics, or parameter-specific guidance beyond what the schema already provides.

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 names a specific verb ('Returns'), the resource ('market regime'), the possible output values, and the asset scope ('crypto perpetual futures'). It does not explicitly differentiate itself from siblings like get_trade_signal or get_trade_call, but the regime-value list makes the core purpose clear.

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 context 'for one crypto perpetual futures' implies when the tool is relevant, and 'Read-only, live exchange APIs' clarifies the nature of the call. However, there is no explicit guidance about when to use this tool versus alternatives, and the get_track_record mention is about validating track record rather than choosing between tools.

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