Compare Schemes

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

No annotations are provided, so the description carries the full disclosure burden. It communicates the comparison dimensions, which is useful, but says nothing about permissions, error behavior for invalid/duplicate IDs, or the shape of the comparison output.

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, front-loaded sentence with no filler. It could have added one clause on output or constraints, but every word earns its place.

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 comparison tool with one well-documented parameter and no output schema or annotations, the description covers intent and comparison dimensions. It stops short of describing what the comparison returns or any input constraints beyond the schema, leaving a modest gap.

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 scheme_ids parameter already documents the 1-5 range with illustrative IDs, so the schema does the heavy lifting. The description's 'up to 5' merely restates the maxItems constraint without adding new semantics.

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 states a specific verb (compare) and resource (government welfare schemes) and scopes it to up to 5 items across named axes (benefits, eligibility rules, deadlines). This clearly separates it from get_scheme/search_schemes, though it never names a sibling explicitly.

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 'side-by-side comparative analysis of up to 5' implies when the tool is appropriate (multi-scheme comparison), but there is no explicit when-not guidance and no alternative tools named for single-scheme lookups or eligibility checks.

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