create_paper_exchange

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

Explains no API keys required, simulated balance, no real money. Discloses OAuth scope and session-cookie user access. No annotations provided, so description carries full burden; adequate but could mention rate limits or limits on number of exchanges.

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 paragraphs, front-loaded with purpose and key benefit. No redundant sentences. Efficiently conveys purpose, auth requirements, and usage context.

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?

Fairly complete for a creation tool. Could mention what the response contains (e.g., exchange ID, status) since no output schema exists, but the use case is clear enough for agent invocation.

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 100%. Description adds meaningful examples (e.g., 'binance' for platform, 'BTC Paper Test' for accountLabel) and clarifies enum values (spot vs futures). Justifies baseline 3 plus extra value.

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?

Clearly states it creates a paper-trading exchange with simulated balance. Distinguishes from siblings like connect_exchange (presumably live). Recommends for first-time users and paper workflows.

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?

Recommends as starting point for first-time users and paper workflows. Mentions auth scope requirements. Does not explicitly state when not to use or compare to alternatives, but context from sibling names implies connect_exchange for live.

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