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

No annotations are provided, so the description carries the full behavioral burden. It discloses what the output describes (finality conditions + proof layout) and its provenance ('Synced from TaifoonV5Types.sol + the spinner mapper'), which signals authoritative, likely static reference data. However, it never states that the call is read-only/side-effect-free or whether out-of-range ids error, so disclosure is partial.

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 with the core purpose front-loaded and supporting detail (proof layout, provenance) trailing. No filler. The provenance clause is slightly tangential but earns some place as a trust signal.

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?

With no output schema and no annotations, the description sensibly names what the explanation will contain, which is the key thing an agent needs to know before calling. For a single-parameter, read-only explainer this is close to complete; the only missing piece is confirming it is non-mutating.

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 must compensate for the single parameter. It does add meaning: the parameter is a 'V5 L6 finality type id' and its valid range is 0-15. But it does not enumerate what the individual ids mean, leaving the id space opaque. This is more than the bare integer schema but not a full compensation.

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 ('Explain') and a precisely scoped resource (a V5 L6 finality type id in 0-15), plus what the explanation covers: block finality conditions and proof layout. It is clearly a read-only explainer, distinct from the action-oriented siblings like taifoon_grid_* and taifoon_hire_*. It does not explicitly name a sibling alternative, so it lands at 4 rather than 5.

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?

Usage is implied: an agent would call this when it needs to interpret a finality type id. There is no explicit when-to-use statement, no when-not-to-use, and no alternative tool named (e.g., a general proof or superroot lookup that might overlap). Adequate but with a clear gap.

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