get_study_comparator

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

No annotations are supplied, so the description carries the full burden. It implies a read via 'Page' but never states that it is non-mutating, what permissions or study state are required, what happens when the comparator is unregistered, or how paging terminates.

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?

It is a single front-loaded sentence with no filler, which is good, but the brevity comes at the cost of substance rather than from tight editing of a complete statement. One additional clause on inputs or return content would have earned 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?

The presence of an output schema excuses it from describing return values, but for a two-required-parameter, study-scoped lookup with zero annotation coverage, the definition leaves the caller guessing about identifier semantics and access conditions. It is not complete enough to invoke confidently without opening the schema.

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 0% across four parameters, so the description must compensate and does not. It never mentions study_id as the scoping key, never defines what a 'comparator' identifier looks like, and only obliquely hints at limit/offset through the word 'Page'.

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 verb 'Page' plus the resource 'registered comparator configuration and its measured model identity' does signal a paginated read of a comparator record, but the phrasing is jargon-heavy and does not clearly separate it from siblings like get_study, get_study_assessment, or get_sample. An agent can guess the general area but not the exact payload.

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, when not to, or which sibling covers an adjacent need. The only usage hint is the implicit 'Page' wording suggesting repeated calls for large result sets.

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