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

Annotations already declare non-read-only, idempotent, destructive, and closed-world behavior. The description adds useful context via the response shape and create/update parameter applicability, but it does not explain what is destructive or what auth requirements apply.

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?

Front-loaded and dense with no wasted sentences. Each sentence contributes purpose, required-field information, optional parameter semantics, or response shape.

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 an 11-parameter mutation with no output schema, the description covers purpose, required field, most parameter semantics, and the response envelope. It is short of fully complete because it omits destructive impact and sibling-tool routing.

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 only 18%, so the description must compensate. It names most optional fields, adds create-only/update-only constraints, and clarifies int64 string formats; the remaining botId and projectApiKey semantics are covered by schema descriptions.

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: 'Create or update a release catalog entry.' The create-vs-update semantics are clear, but it does not explicitly differentiate this from the sibling get-release tool.

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?

Provides clear context for using this tool to create or update releases, including create-only environment and update-only branchId constraints. It does not name an alternative or give explicit when-not guidance, such as using get-release for retrieval.

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