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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds nothing on top — no pagination behavior, no result-volume caveat, no ordering or filtering semantics — so it contributes no behavioral value beyond the annotations.

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?

Two short, front-loaded sentences with no padding. The trailing "GET /api/v2/bot/signal/cex" is redundant implementation detail that an agent does not need, a minor non-earning sentence, but the overall size is appropriate.

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?

This is a low-complexity, zero-parameter read, so the description is nearly adequate. However, with no output schema, the description carries the burden of conveying the return shape and whether the listing is paginated or bounded; "get all" hints at an unpaginated collection but leaves result size and empty-result behavior unstated.

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 takes zero parameters, which is the baseline-4 case; there is no parameter semantics to clarify and the schema is empty by design (schema coverage reported at 100%). Nothing in the description is needed to invoke it correctly.

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?

"Get all CEX signal bots" gives a clear verb (get) plus resource (CEX signal bots) and implies collection scope via "all". It does not, however, distinguish itself from close siblings such as get_bot_signal_cex_id (single bot), get_bot_signal_cex_total (counts), or get_bot_signal_dex / get_bot_signal_prediction — the agent must infer the boundary from naming conventions alone.

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?

No when-to-use context, no exclusions, and no alternatives are named. With five sibling list/get tools in the bot_signal family, the description offers no routing guidance about when this collection read is preferable to the _id, _total, or _dex/_prediction variants.

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