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

With no annotations at all, the description carries the full behavioral burden and falls short. It does not disclose that this is a state-changing operation that commits funds, what it returns (transaction ID, deposit address, expiry), any auth/API-key requirement, or error behavior (invalid pair, amount below minimum). Only the platform name 'Flashift' is added beyond the title.

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 front-loaded sentence with no filler or repetition. It is efficient, though the brevity reflects under-specification more than disciplined editing.

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 high-complexity mutation tool: 10 parameters, 8 required, no annotations, and no output schema. An agent needs to know the quote prerequisite, what a successful call returns, and how failures surface; none of that is present, so the definition is not complete enough to invoke confidently.

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%, so every parameter is already documented in the schema, including the get_estimated_amount dependency for provider_name. The description adds no parameter-level meaning beyond that, so the baseline 3 is 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?

The description states a specific verb and resource: 'Create a new cryptocurrency exchange/swap transaction on Flashift.' That clearly separates it from the read-only siblings (get_transaction_info, get_currencies). It does not, however, name or contrast itself with any sibling explicitly, so it stops short of a 5.

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 conditions, prerequisites, or alternatives are given. Critically, the description omits that provider_name must be selected from get_estimated_amount (that link only appears buried in the schema) and says nothing about needing a confirmed quote before creating a transaction.

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