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

With no annotations provided, the description carries the full burden and partly meets it by listing the specific validation checks (iXBRL/XHTML, taxonomy, mandatory fields, etc.). However, it does not disclose return behavior, whether any action is taken (e.g., archiving), or any side effects, leaving gaps in transparency.

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 a single dense sentence that front-loads the core purpose and then lists specific check items. Every part adds value and there is no redundant or filler content.

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?

The description covers the scope of validation well but omits the return value/output format, which is important since no output schema exists. It also leaves the relationship to sibling tools implicit, making it adequate but not fully complete.

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%, so parameters (url, format, token_symbol) are already documented. The description adds only high-level context about format and token but no additional parameter-level detail, so it stays at the baseline.

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 uses a specific verb ('Validate') and resource ('crypto-asset whitepaper'), with explicit legal references (MiCA Art. 6(10)-(11), ITS 2024/2984). This clearly distinguishes it from sibling tools like assess_token or gap_report, even though no alternative is named.

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 implies the tool should be used when whitepaper validation against MiCA/ITS is needed, but it does not explicitly state when to use it over alternatives (e.g., assess_token, readiness_check) or provide exclusion criteria.

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