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

Annotations already declare readOnlyHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds real behavioral context beyond them: the data originates from the contract's own on-chain record (authoritative, not cached metadata) and results are ordered oldest first. It stops short of disclosing whether history is paginated, truncated, or what a non-existent token_id yields.

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?

One sentence that front-loads the resource and data source before the categorical detail. The loan-state parenthetical (funded, repaid, defaulted, refinanced, extended) is dense but each term conveys scope; only the trailing "plus the chain of holders and the sale prices" partially repeats "sale and price" already listed.

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, single-parameter tool with no output schema and no annotations gap, the description is nearly sufficient: it defines subject, source, ordering and contents. The remaining gap is practical completeness, i.e. how large the returned history may be and whether callers must paginate.

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% for the single token_id parameter, so the schema contributes nothing about format. The description only implies token_id selects "one Pusaka"; it never states the expected format (numeric id vs. address) or whether it must correspond to an existing token.

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?

"Provenance of one Pusaka from the contract's own on-chain record" names a specific resource and scope, then enumerates exactly which events are returned (mint, listing, sale, transfer, inheritance, loan states, withdrawal) plus holders and sale prices. That enumeration makes the boundary against siblings like pusaka_inspect or pusaka_overview self-evident even though none 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 phrase "one Pusaka" and the required token_id imply this is the single-token detail call, but there is no explicit when-to-use statement, no when-not to prefer such alternatives, and no note on preconditions or cost of a full history read. Usage is inferable rather than stated.

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