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

With no annotations, the description carries the full burden and does well: it discloses that this is a write operation, that the key is returned only once (a critical, non-recoverable behavior), and the exact set of values returned including provider base URLs. It does not address idempotency, name collisions, or key revocation/rotation, which keeps it short of a 5.

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?

Two tight sentences, front-loaded on the action and followed by the return payload, with no filler. The phrase 'with no form' is slightly cryptic but conveys that no UI/input flow is required, so it earns its place.

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?

There is no output schema, and the description compensates by enumerating the return payload (key, base URLs, dashboard link, badge URL) plus the billing posture. Remaining gaps are edge cases — whether the key is retrievable later and behavior on duplicate names — that are minor for a one-parameter provisioning tool.

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 coverage is 100% and the single 'name' parameter is fully documented in the schema with its default, so baseline 3 applies. The description adds nothing about naming semantics (e.g., uniqueness, whether the name affects the returned URLs), so it does not exceed the 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 concrete verb and resource ('Create a TokenZero workspace and key') and even enumerates the artifacts produced, so the agent knows exactly what the call yields. Sibling tools (audit_repo_token_waste, workspace_metrics, etc.) are clearly different operations, though the description does not explicitly contrast itself with them.

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?

'with no form' and 'Free up to the monthly free tier; nothing is billed' imply this is the frictionless, zero-cost way to bootstrap a workspace, which is useful usage context. However, there is no explicit when-to-use/when-not statement or mention of prerequisites such as whether a workspace must already exist for the sibling metrics/audit tools.

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