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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and closed-world scope, so the safety profile is covered. The description adds that the data is 'verified' and carries effective dates and legal references, which signals authority and currency, but says nothing about caching, scope limits, or freshness beyond that.

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 dense sentence that front-loads the core claim ('The verified programme data') and then lists contents. Every clause maps to a real section of the tool, though the trailing enumeration is long enough to border on a data dump.

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-enum-parameter facts tool with a full schema and no output schema, the description adequately signals what is returned by listing the content categories. Missing only language/locale or versioning caveats, which are not clearly needed here.

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% and the single enum parameter is fully documented in the schema, so the baseline is 3. The description's content list loosely maps onto the enum values (fees, requirements, process, documents, dependants), adding marginal value but no formatting, default, or selection guidance beyond 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 names a specific resource (MPRP programme data) and enumerates its contents: property thresholds, fees and contributions, requirements, application steps, documents, dependant rules. That lets an agent distinguish it from siblings like calculate_mprp_cost or get_property. It stops short of explicitly naming an alternative, but the resource is unambiguous.

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 when-to-use instruction, no prerequisite, and no mention of alternatives such as calculate_mprp_cost for cost computations. The content list implies what the tool covers but leaves routing entirely to inference.

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