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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the destructive nature is covered by structured data. The description adds nothing beyond a restatement of the action and the REST path; it does not say whether nested signals/folders are removed, whether deletion is reversible, or what auth is required.

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?

A single terse sentence with the action front-loaded, followed by the endpoint path. No padding, though the raw REST path is largely redundant to an agent that already has the tool name.

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 single-parameter delete with destructive annotations and no output schema, the minimum needed to invoke correctly is present. However, nothing addresses cascading effects or irreversible loss, which is the main thing an agent would want to know before calling a delete.

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?

Only one parameter (id) and schema description coverage is 100% ('Folder ID'), so the schema carries the semantics. The description adds no format, scope, or sourcing guidance for the ID, making the baseline 3 appropriate.

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?

States a specific verb (Delete) and resource (DEX signal bot folder), and the 'DEX' qualifier implicitly separates it from the CEX and prediction folder siblings. It is clear what the tool does, though it never explicitly contrasts itself with those siblings.

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 indication of when to use this versus alternatives (e.g., moving to the folder's PUT sibling, or which folder/ID to supply). Nothing is said about preconditions or what happens afterwards.

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