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

The annotations already disclose that this is not read-only, is open-world, is not idempotent, and is not destructive. The description adds only that the result is a drafted plan with stages, but it does not explain side effects, persistence, permissions, or what 'drafting' changes in the workspace.

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 short and front-loaded, with the core operation stated first and the return shape second. The second sentence is somewhat redundant because an output schema exists, but the overall structure has little waste.

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 five-parameter, open-world, non-idempotent drafting tool with no parameter documentation in the schema, the description is too thin. The output schema covers return values and annotations cover safety flags, but the description still omits prerequisites, effects, and parameter meanings.

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 0%, so the description needs to compensate for five undocumented parameters. It only loosely maps 'ticket or repository' to `derived_from_ticket` and `source_repo`, leaving `workspace_id`, `environment`, and `cicd_provider` 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?

It states a specific verb and resource: 'Draft a deployment plan,' and identifies the source as 'a ticket or repository.' That is clear enough to understand the basic operation, but it does not distinguish this from the related sibling `generate_cicd_workflow`.

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 gives no explicit when-to-use guidance, prerequisites, or alternatives. Mentioning that the plan is drafted from a ticket or repository only hints at the input context and does not tell an agent when to choose this tool over its siblings.

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