get_v1_bittensor_derivatives_alpha_prices

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

With no annotations, the description carries the transparency burden. It discloses that data is 'Informational research data — not investment advice' and notes the tool cost ('Price: $0.02'). It does not detail update frequency or authentication, but the simple read operation is adequately explained.

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 concise (four sentences) and front-loaded with the key purpose. Every sentence adds value: purpose, scope, use cases, and disclaimer/metadata. No redundant or trivial text.

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?

Given zero parameters and no output schema, the description is fairly complete. It covers what data is returned (prices for all subnets), use cases, and a disclaimer. It lacks an example or detail on data format, but for a simple read endpoint it is sufficient.

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 input schema has zero parameters, so the description's role is to explain what the tool returns. It states 'Latest alpha-token price per Bittensor subnet (TAO + USD). All 129 subnets in one call,' which adds meaning beyond the empty schema. However, it does not specify the output format or fields.

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 clearly states it provides the latest alpha-token price per Bittensor subnet (TAO+USD) for all 129 subnets in a single call. It distinguishes from siblings like get_v1_bittensor_derivatives_alpha_price_history_netuid (history for a specific netuid) and get_v1_bittensor_derivatives_subnets_all (subnet list, not prices).

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 description implies usage for cross-subnet price arbitrage and dTAO portfolio rebalancing, but does not explicitly state when not to use or compare to alternatives. The phrase 'All 129 subnets in one call' suggests it is a bulk endpoint, providing clear context for selection.

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