createCopyMt5Bind

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

Without annotations, the description carries the full burden. It discloses that the tool creates a binding, forwards to downstream validation, and may fail for specific business reasons presented as MCP tool errors. It mentions the success response includes a link and guides the agent's reply. However, it doesn't explicitly state destructive nature or auth requirements, but the creation act implies mutation.

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 is excessively long due to a multi-paragraph agent hint that includes detailed workflow instructions, success message templates, and link construction. While valuable, it is not concise; the front-loading is good but the later sections could be condensed. Every sentence earns its place but overall density is high.

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, the description covers business logic and failure modes well. It provides success message formats and link construction, but fails to describe the tool's actual return value (likely a binding ID or status). The agent hint focuses on user interaction rather than tool output, leaving a gap in understanding what the tool returns.

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 coverage is 0%, so description must add meaning. It defines providerMark as the target and gives an e8 amount example for investmentE8 (e.g., 30000000000 for 300 USDT). However, it doesn't explain the concept of e8 or the minimum value from the schema. It adds some value but not exhaustive documentation of parameter semantics beyond what the schema node provides.

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 first sentence clearly states the tool creates a Copy Trading TradFi follow binding with specific parameters (providerMark and investmentE8). It unambiguously identifies the verb 'create' and the resource 'Copy Trading TradFi follow binding', distinguishing it from siblings like createCopyTradeBind by targeting TradFi specifically.

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 description provides explicit guidance: use only after obtaining an exact providerMark, not inferring from display name; minimal endpoint does not support optional parameters like TP/SL; and the agent hint outlines a complete workflow for recommending and binding, including when to call other endpoints. It also lists common business failures, helping the agent decide when to use this tool.

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