e2e_create_bucket

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 beyond the mutation itself. It does not state permission requirements, whether bucket names must be globally unique, whether creation is idempotent, or that flags like Object Lock and Versioning are effectively irreversible once set at creation time.

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?

A single short sentence with zero waste and the core action front-loaded. It is efficient, though arguably too terse for a creation tool with six configuration options.

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 six-parameter resource-creation tool with no annotations and no output schema, the description is thin. It omits the uniqueness constraint on bucket_name, the required project scope, and the irreversible nature of the creation-time options, leaving the agent under-equipped to call it correctly.

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%, so all six parameters are already documented in the schema and the baseline of 3 applies. The description adds no parameter-level meaning, such as how location interacts with project_id or the consequences of the lock/encryption/versioning flags.

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 (Create) and resource (bucket), and expands the EOS acronym to 'E2E Object Storage', which is genuinely useful since the name uses an unexplained abbreviation. It does not explicitly distinguish itself from e2e_delete_bucket or e2e_list_buckets, but the verb makes the distinction obvious.

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 tool versus alternatives, no prerequisites (project_id, credentials, quota), and no note on what to do if the bucket already exists. The agent must infer everything from the schema.

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