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

With no annotations, the description carries the full behavioral burden. It usefully discloses zero-retention processing and a signed Ed25519 VC, but it does not explain whether raw text is transformed or blocked, what the signed VC contains, authentication needs, or how the result is returned.

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 front-loaded phrase with no wasted sentences, so it is concise. It is somewhat dense with acronyms (IBAN, HRB, VC), which slightly reduces clarity, but the core purpose comes first.

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 three parameters, no annotations, 33% schema coverage, and no output schema, the definition is too thin. It omits the roles of two parameters and does not clarify the return behavior of the signed VC, leaving meaningful gaps for an agent to call it correctly.

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 only 33%, and the description does not compensate. raw_text is described in the schema and its PII categories are implied in the description, but max_accepted_fee_eur and ap2_intent_mandate_id receive no meaning in either place.

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 states a specific verb and resource: GDPR PII redaction on text, with named PII categories and a signed Ed25519 VC. It is clear enough to distinguish from the sanctions/KYB and e-invoice siblings by domain, but it does not explicitly differentiate itself from them.

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?

There is no explicit guidance on when to use this tool versus alternatives, nor when not to use it. The word 'gate' weakly implies preprocessing, but the description leaves the agent to infer the workflow context.

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