audit_pmc_methodology

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

With no annotations, the description carries the full behavioral burden. It usefully discloses that it pulls external Europe PMC XML and that no scientific conclusion, risk-of-bias judgement, or absence claim is inferred, which meaningfully bounds interpretation of results. It still omits auth requirements, failure behavior when a PMC ID is invalid, and what the validation result contains.

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?

Two short sentences, front-loaded with the action before the limitation. The second sentence is a slightly awkward fragment, but nothing is padded or wasted.

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?

A tool taking four required, undocumented arguments with no output schema and no annotations needs more than two sentences. The description never explains the annotation format, what 'outcome' and 'study_design' should contain, or how validation findings are returned.

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?

All four parameters are required with 0% schema description coverage, and the description mentions none of them. The non-obvious 'annotations' array of free-form objects and the 'outcome'/'study_design' strings are left entirely unexplained in both the schema and the prose.

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 two specific actions (fetch Europe PMC XML, validate user annotations) against a concrete resource (direct JATS paragraphs), which is far more informative than a bare 'audit' label. It does not, however, distinguish this from the sibling 'audit_methodology', so an agent cannot tell the two apart from the text alone.

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 statement of when to use this tool versus the similarly named audit_methodology, no prerequisites, and no conditions that select it over alternatives. The only scoping present is a negative claim about what is not inferred, which bounds output rather than guiding selection.

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