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

The annotation already declares readOnlyHint=true, and the description usefully adds that the register is append-only and read by sequence number. It still omits ordering guarantees, whether reads are paginated, and what the default window is when 'da' is omitted.

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?

A single efficient sentence with the resource and scope front-loaded and no filler. It is concise, though arguably too terse given the missing parameter and usage detail.

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 read-only list tool with annotation coverage and no output schema, the description is minimally adequate. It nonetheless leaves gaps on defaults, limit semantics, and ordering that an agent needs to invoke 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 description coverage is 0%, so the description carries the full burden. It gestures at the 'da' parameter ('a partire da un numero di sequenza') but says nothing about 'limite' (max 500) or the default behavior when both are absent, leaving half the parameters undocumented.

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 verb and resource ('Legge righe del registro pubblico append-only') plus the reading mode ('a partire da un numero di sequenza'), so the agent knows this is a sequential read of a register. It does not, however, distinguish itself from siblings like verifica_registro or cerca_archivio, which sound closely related.

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 statement of when to use this tool versus cerca_archivio (search) or verifica_registro (verification), nor any prerequisites. The agent must infer usage purely from the word 'Legge'.

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