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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed world, so the safety profile is covered. The description adds the shape of the result (title, canonical URL, evidence-review date), which is genuinely useful, but says nothing about result volume, ordering, or pagination for a full-corpus listing.

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 sentence with zero filler, front-loaded with the verb and scope, and the returned fields appended as a compact list. Nothing is redundant or padded.

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 input parameters and no output schema, the description carries the burden of describing what comes back, and it does list the three returned fields. It is nearly complete; only guidance on result size/ordering/pagination for a full-corpus listing is missing.

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?

The tool takes zero parameters, so by rule the baseline is 4. The description correctly adds no parameter detail because there is none to add, and nothing in the schema is left unexplained.

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 (List) and resource (clinician teaching modules and patient chapters) and even enumerates the returned fields. The word 'every' signals an exhaustive enumeration, which implicitly separates it from read_module and search_teaching, but no sibling is named explicitly, keeping it just below the top score.

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?

Usage is only implied: an agent can infer this is the tool for dumping the full catalog rather than fetching one module or searching. There is no explicit when-to-use statement, no exclusions, and no mention of search_teaching/read_module as alternatives.

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