create_environment

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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the safety profile is covered. The description adds real value in the encoding caveat about JSON string fields and the endpoint, though it does not disclose what side effects occur (secret storage, sync initialization) or auth requirements.

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?

Three short sentences with the action front-loaded and no filler. The endpoint is arguably redundant with the tool name but is harmless and useful for API-literate callers.

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 destructive, non-idempotent write with a large nested body, no schema descriptions, and no output schema, the description is too thin. An agent must guess which body fields exist and what the response will be.

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% and the body carries roughly a dozen fields, yet the description only says 'supply API fields in body' and warns that JSON-encoded string fields must remain strings. It never mentions name (the only required body field), project_id, secrets, or sync settings, so it does not compensate for the undocumented schema.

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 ('Add environment') plus the underlying endpoint POST /project/{project_id}/environment, so an agent knows exactly what resource is created. It does not differentiate from siblings such as update_environment or sync_environment, which keeps it below a 5.

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 versus update_environment, sync_environment, or delete_environment, and no preconditions (project permissions, whether the environment must not already exist) are stated. 'Add' implies creation, but that inference comes from the name rather than the description.

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