get_study_case_messages

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

With no annotations, the description still discloses two meaningful traits: results are bounded and holdout text is never returned. It omits pagination behavior beyond the word "bounded" and says nothing about permissions or error cases (e.g. holdout case requested).

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 front-loaded sentence with the exclusion clause trailing for emphasis; nothing redundant or bloated.

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?

An output schema exists, so return values need no prose, but with six undocumented parameters, no annotations, and an unusual two-level pagination scheme (message paging plus content paging), the definition leaves too much unexplained for an agent to page correctly.

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 0% across six parameters, so the schema names only (limit, offset, content_limit, content_offset, case_id, study_id) carry all meaning. The description's word "bounded" faintly gestures at pagination but explains none of the four paging parameters or their defaults.

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 and resource ("Read bounded chat messages") and narrows scope ("for development cases only; never sealed holdout text"). It does not differentiate itself from siblings such as get_study_case_spec or get_study_cases, but the read scope 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?

Gives a clear when-to-use condition (development cases) and an explicit exclusion (sealed holdout text), which is the critical guardrail. It names no alternative tool for other content types, leaving the agent to infer siblings.

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