hl_spot_meta

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the resource type and does not mention read-only safety, return shape, performance, or any operational characteristics. The phrase 'metadata' implies a read operation, but no explicit behavioral detail is given.

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, concise fragment with no wasted words. It is appropriately sized for a simple metadata endpoint, though it could be slightly more informative. It is not overly verbose and is easy to parse.

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 zero-parameter tool with an output schema, the description need not explain return values. However, it lacks context on how this tool compares to similar siblings (e.g., hl_meta, hl_spot_meta_and_asset_ctxs), which is a notable gap. The description is minimally adequate but leaves the agent uncertain about which metadata endpoint to choose.

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 tool has zero parameters, and the schema coverage is trivially 100% with an empty object. There are no parameter semantics to explain, so a baseline score of 4 is appropriate; the description adds nothing about parameters because there are none to describe.

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 'Spot pair metadata (spotMeta)' clearly identifies the resource (spot pair metadata) and is not a tautology of the tool name. It is clear about what the tool provides, though it lacks an explicit verb and does not differentiate from the sibling hl_spot_meta_and_asset_ctxs.

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 guidance on when to use this tool versus alternatives. The description does not mention that this returns all spot pairs, nor does it distinguish from similar metadata endpoints like hl_meta or hl_spot_meta_and_asset_ctxs.

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