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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, openWorld). The description goes further with non-obvious domain behavior: gap subtotal excludes interview/placement fees, anonymous providers must stay locked, candidates are not auto-approved, and output is English natural-language text with sources/conditions/pagination preserved. No contradiction with the read-only annotations.

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?

Purpose is front-loaded in the first clause, followed by quote behavior, fee caveat, guardrails, and output format – each sentence carries distinct information with no filler.

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?

With no output schema and seven parameters, the description usefully states the return language (English natural-language text), preservation of sources/conditions, and pagination, plus the quote caveat. It is nearly complete for a read tool, though the roles of the three undocumented ID/pathway parameters remain unaddressed.

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 57%: slug, gapUnits and residency are described inline, but pathway, onlineTierId and providerPublicId are undocumented. The description adds partial meaning by naming the RPL/gap/online price dimensions (mapping loosely to pathway) and the fee-exclusion rule, but it does not explain how to obtain or use the undocumented identifiers, so it only partially compensates.

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 opens with a specific verb ('Read') and enumerates the resource contents: qualification requirements, risks, sources, public providers, and RPL/gap/online prices. Keying on 'exact slug' signals a single-record lookup, though it never names the sibling search_rpl_qualifications that produces the slug (that link only appears in the schema).

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?

It states that optional selections yield an indicative quote and that missing choices stay explicit, which implies partial-input behavior. However, it never says when to call this versus search_rpl_qualifications, nor which optional parameters are required for a full quote – usage is inferred rather than spelled out.

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