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

No annotations provided, so description carries full burden. It discloses the read-only listing behavior but omits return format, pagination, filter combination semantics, and any large-data caveats. Since 'List' implies non-mutating, safety isn't the issue; the lack of behavioral detail for a potentially large collection is a gap.

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?

Single well-formed sentence, front-loaded with action and scope; no wasted words.

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?

Tool has 4 optional params, no output schema, no annotations. Description fails to specify what fields are returned, how filters combine, or pagination behavior. It's adequate as a one-liner but incomplete for autonomous 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 only 25%; description only says 'optional filters' without defining country/service_type/filter semantics. The enum for criticality is in schema, but description adds no clarification for combining filters or accepted values.

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 clear action 'List all ICT third-party providers' with scope 'Register of Information' and optional filters. Distinguishes from sibling get_provider (single) and register_provider (creation).

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?

Clear context: use to retrieve all providers, optionally filtered. Does not explicitly name alternatives or exclusions, but 'list all' contrasts with get_provider.

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