get_stablecoin_access

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

The description goes beyond read-only annotations by disclosing the 2026-07-01 CASP cliff, that restrictions bind venues not people, self-custody rights, and default behaviors (global status without country). It also notes auto-injection of warnings into other tools. This adds substantial context but doesn't detail rate limits or auth.

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 very long and front-loads a verbose Chinese query pattern before stating the tool's function. The core purpose is buried after a list of user questions, making it hard to parse quickly. It could be significantly trimmed without losing key information.

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 the complexity of MiCA regulations and the lack of an output schema, the description provides necessary context on return values, default behavior, and regional nuances. It covers what the tool returns and how it interacts with other tools, though it could be more structured.

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 the schema already explains asset, country, exchange, and language thoroughly. The description adds minor context about default asset (USDT) and country omission, but largely repeats what's in the schema.

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 clearly states it returns MiCA regional access status for a stablecoin, enumerating specific outputs like issuer authorization, venue trading restrictions, and alternatives. However, the Chinese preamble (a long user-query pattern) is verbose and the core purpose doesn't cleanly distinguish from siblings like compare_countries or get_withdrawal_fees that might also touch on regional rules.

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 Chinese text gives example user questions (trading USDT, MiCA compliance, Revolut), implying usage context, but there is no explicit 'when to use this vs alternatives' instruction. The mention of auto-injection into other tools is helpful but not framed as a call guideline.

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