get_ct_latest_version

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

With no annotations, the description carries the behavioral disclosure burden. It states that the tool returns a dictionary with standard, latest version, display version, and available versions, which is useful. However, it does not disclose error behavior for invalid standards, case sensitivity, or any other side-effect-relevant traits.

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?

The description is compact and well-organized with labeled Args, Usage, and Returns sections. The purpose is front-loaded and every line contributes useful information without 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?

For a simple getter with no annotations and no output schema, the description covers the core return shape and the main parameter. It is incomplete around the undocumented `headers_` parameter, invalid-input behavior, and how this tool relates to sibling latest-version getters.

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 description explains the `standard` parameter with valid examples and notes the SDTM default, compensating for the 0% schema coverage for that parameter. However, the `headers_` parameter in the schema is completely undocumented in both the description and schema, leaving one of two parameters 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?

The first line states a specific action and resource: 'Get the latest Controlled Terminology version for a CDISC standard.' It names example standards and describes the return value. It does not explicitly contrast with sibling tools like get_sdtm_latest_version, but the 'Controlled Terminology' resource focus is distinct enough.

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?

The 'Usage' section gives call examples but no guidance on when to choose this tool over sibling tools such as get_sdtm_latest_version, get_cdashig_latest_version, or get_sendig_latest_version. There are no exclusions, prerequisites, or alternative-selection conditions.

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