Get the EU trader status steps

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

With readOnlyHint=true already set, the description adds real value: it discloses that the tool does not actually mutate anything ('Not API-addressable') and that it returns steps plus a deep link, which corrects the misleading 'set_' naming. 'Pro feature' also flags access gating. It stops short of describing the return payload's shape.

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 tight sentences that front-load the resource and immediately correct the misleading name. Every clause earns its place with no filler.

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 single-parameter, read-only guidance tool with no output schema, the description covers the essentials: what it relates to, that it is not API-addressable, and what it returns. Minor gap is the absence of any note on how the returned steps should be consumed or presented.

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?

There is a single parameter (app_id) with 100% schema description coverage, so the schema already carries the semantics. The description adds nothing about the parameter, so the baseline of 3 applies.

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?

States a specific resource (EU DSA trader status) and clarifies the actual behavior: it returns the steps and a deep link rather than performing the change implied by the name 'set_eu_trader_status'. This is clear, though it does not differentiate itself from related guide siblings like asc_guide or asc_setup_check.

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 phrase 'Not API-addressable' tells the agent this is a guidance-only tool, which is genuine usage context, but there is no explicit when-to-use guidance and no alternatives named. Usage is implied rather than stated.

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