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

No annotations are provided, so the description carries the full burden. 'Queries' implies a read-only operation, but the description does not disclose what a concordance result contains, whether it maps provisions across the four codes, or any limits on lookup. For a tool with zero annotation coverage, this leaves the agent guessing about behavior.

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, front-loaded with the verb and the cross-jurisdictional scope, with no filler. It is efficient, though it could have used the remaining space to answer the usage and output questions.

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 cross-jurisdictional concordance tool with no output schema and no annotations, the description omits what the returned concordance looks like and what constitutes a valid topic key beyond the schema's example. It is thin for the conceptual complexity of the operation.

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 100% and the single parameter is documented with a concrete example ('conformite_marchandises'). The description adds only 'for a given legal topic,' which restates rather than extends the schema, so the baseline 3 is appropriate.

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 ('Queries') and resource ('statutory concordance') and names the four legal frameworks covered, which lets an agent see it is a cross-jurisdictional lookup rather than a procedural/deadline tool. It does not explicitly differentiate itself from sino_cietac_clause, sino_defect_notice, or sino_inspection_delay, but the subject matter is clearly distinct.

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 its siblings or when it is inappropriate. The phrase 'for a given legal topic' implies a lookup context but gives no routing guidance, no prerequisites, and no note on how topic keys are chosen.

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