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

With no annotations, the description carries the behavioral burden, and it does disclose meaningful behavior: the output includes a full score read, an awareness block with sector money flows, coiled setups with coil_score range, and rows shaped by the payload's schema block. It also notes the date after which the awareness block is included. It does not mention latency, auth, or rate limits, but for a zero-parameter read the content disclosure is strong.

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 front-loads the core ranked-list result and then adds the sibling, the awareness-block change, and the schema contract in compact sentences. Every sentence adds information, though the dense jargon ('x402', 'coverage', 'board-tier') takes some decoding.

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 no output schema and no annotations, the description provides the main contract: top 10 per book, ranking criterion, full score read, awareness block components, coil_score range, and a pointer to the payload schema for field names. It leaves some domain terms undefined (book, leadership names, coverage), but an agent can still understand what the tool returns and how it differs from the live variant.

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, so there is nothing for the description to elaborate beyond the empty input schema. Per the baseline rule for no parameters, no additional parameter semantics could improve this definition.

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 opens with a clear, specific deliverable — the top 10 leadership names per book ranked by opportunity score — and defines the selection criteria (confirmed uptrends) and the fields returned. It also distinguishes itself from the live sibling by name and cost caveat, though it does not contrast with other list-like siblings such as get_buy_list or get_rotation.

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 only usage signal is the mention of a live sibling with a pay-per-call cost, which implicitly suggests the non-live tool for routine or cost-conscious reads. No explicit when/when-not guidance is given, such as 'use this for the daily snapshot, use live for intraday'.

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