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

Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=false, and the description usefully adds that the message triggers real order execution on a webhook, which is the key consequence. It stops short of disclosing delivery behavior, failure handling, or what happens when the hash/key is invalid, so it does not meaningfully exceed annotation coverage.

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 sentences, front-loaded with the verb and target, with no filler. The second sentence slightly restates 'send' from the first, but it earns its place by naming what is actually transmitted and why (execution).

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 destructive, nested-payload, no-output-schema tool that can trigger live order execution, the description is minimal: it does not explain post-invocation behavior (results going to the optional callback), nor how it relates to send_data_hook_message. The rich schema and annotations carry most of the load, leaving this adequate but thin.

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?

Schema description coverage is 100% and the nested payload (symbol, side, size, flags, callback, dilution, forceSize) is documented in detail in the schema itself. The description adds nothing parameter-level, so the baseline 3 applies even though it gestures at 'trading signals, trading orders'.

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 names a specific verb (send) and resource (a message to the bot hook) and clarifies the payload can be trading signals or trading orders delivered to a webhook for execution. That is clear, but it never differentiates itself from the near-identical sibling send_data_hook_message, so an agent must infer the split from the tool name 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?

There is no explicit when-to-use guidance and no mention of alternatives such as send_data_hook_message, which is the obvious competing tool. The description only implies the tool's domain (trading signals/orders to a webhook) without stating prerequisites or selection criteria.

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