get_cdashig_latest_version

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

With no annotations, the description carries the full burden; it does indicate an external API call, optional custom headers, and the returned fields ('latest version, all available versions, and display version'). However, it doesn't disclose auth expectations, failure behavior, or that the call is read-only beyond the verb 'Get'.

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 docstring is tight and well-organized with Args, Returns, and an Example, front-loading the purpose in the first line. The example is helpful but has a name typo ('get_cdash_latest_version' instead of 'get_cdashig_latest_version'), which slightly reduces trust.

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 one-optional-parameter retrieval tool, the description covers the main input, return shape, and an example, so an agent can call it without opening the schema. The gap is the unresolved type mismatch and the absence of any note about API errors or required authentication, which matters because no annotations or output schema exist.

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 adds that headers_ is optional and holds custom headers for the API request, which is meaning beyond the bare schema. But it contradicts the schema by typing it as 'dict' while the input schema declares type string, which can mislead an agent into sending an invalid value.

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 opening sentence names a specific verb ('Get'), a specific resource ('latest CDASH-IG version'), and the source API, so an agent knows exactly what the tool returns. This is distinct from sibling tools like get_ct_latest_version or get_sdtm_latest_version, which target other CDISC standards.

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 description implies the tool is for CDASH-IG version retrieval, but it never explicitly states when to choose it over get_ct_latest_version, get_sdtm_latest_version, or other siblings. There is no when-not-to-use guidance or exclusion, so routing must be inferred from the resource name.

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