compare_alio_articles

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

No annotations are provided. The description adds that the output is side-by-side, but does not disclose whether the operation is read-only, authentication needs, or the nature of the return result beyond 'side-by-side'. More behavioral detail would be beneficial.

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?

The description is two sentences: one stating the core function and one clarifying the distinction from a sibling. Every sentence adds value with no redundancy.

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?

Given no output schema, the description mentions the output is side-by-side, which is helpful. It is complete enough for a comparison tool, though more detail on output format could improve completeness.

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 is 100%, so baseline is 3. The description adds that 'pair' refers to two specified regulations and 'article' is the same article number, which is already implied by the schema. No additional format or semantics are provided beyond what's in the schema.

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?

The description clearly states that the tool compares the same article number of two regulations 1:1, and explicitly distinguishes itself from compare_alio_regulations which does topic N:N. The verb 'compare' and resource 'same article of two regulations' are specific.

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 description explicitly contrasts with compare_alio_regulations, telling when to use this tool (article-level comparison) versus the sibling (topic-level). However, it does not mention when not to use it or other alternatives like compare_articles.

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