pre_release_versions_get_instance

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing. It does not state that this is a read-only operation, what permissions or scopes are needed, how include/fields affect the response, or what errors occur for a bad id. Repeating the path conveys no behavior.

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 short, but not concise in a useful sense: the parenthetical duplicate of the same path is pure waste, and the remaining text is under-specified rather than economical. Nothing is front-loaded beyond an HTTP verb and route.

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 tool with six parameters including sparse-fieldset and relationship-inclusion options, no output schema, and zero annotation coverage, the description should explain what is returned and how the include/fields parameters shape it. It provides none of that, leaving the agent to infer everything from parameter names.

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 100% across all six parameters, each with its own description (id, include, fields_apps, limit_builds, fields_builds, fields_preReleaseVersions). Per the rubric, high coverage establishes a baseline of 3 even though the description itself adds nothing about parameter meaning.

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 is the raw endpoint path 'GET /v1/preReleaseVersions/{id}' repeated twice, which effectively restates the tool name. It implies retrieving a single pre-release version, but offers no plain-language statement of the purpose and no differentiation from siblings like pre_release_versions_get_collection or pre_release_versions_builds_get_to_many_relationship.

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 guidance on when to use this single-instance fetch versus the collection endpoint or the relationship endpoints. The path alone implies 'fetch by id', but no alternatives, prerequisites, or exclusions are mentioned.

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