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

Goes well beyond the annotations: it discloses the one-time claim link, the 7-day expiry, deletion of unclaimed workspaces, the 3-per-day-per-network rate limit, that no personal details are taken, and the free-vs-paid boundary. These are exactly the operative facts an agent needs before calling a non-idempotent creation tool.

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 core action and the return value are front-loaded, and every clause (expiry, deletion, pricing, rate limit) carries real information. It's a dense paragraph rather than a scannable list, but nothing is wasted.

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?

With no output schema, the description fully carries the return contract (a claim link plus what opening it does) and adds the lifecycle and rate-limit constraints. Nothing an agent needs in order to call it correctly is missing.

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 each parameter's schema description already covers defaults, enum meaning and the length cap. The description only restates that the three parameters are optional, adding no new semantics, so the baseline 3 applies.

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 a new Jobsite workspace') plus the defining scope constraint ('holds only sample data ... nothing real'). No sibling tool does anything similar, so an agent can select this unambiguously.

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?

Explains the triggering situation clearly: 'so they can try Jobsite without setting anything up', and adds the free-sample vs paid-real-workers boundary. It doesn't name an alternative tool, but none of the siblings overlaps, so there's little to exclude.

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