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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is well covered. The description adds useful contextual scope about what the status includes, but it does not disclose any behavioral caveats such as data freshness, permission requirements, or return format. With the annotations present, this is adequate but not exceptional.

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 one informative sentence followed by a practical-use sentence, with no wasted words. The long enumerative list makes it a bit dense, but each item adds value and the primary purpose is front-loaded.

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 no-parameter, read-only status tool, the description is complete enough: it names the covered setup areas, gives concrete use cases, and aligns with the annotations. It does not describe the response shape, but since there is no output schema and this is a simple status getter, that is a minor gap rather than a blocking omission.

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?

The tool has zero parameters and zero required parameters, with 100% schema description coverage. There is no parameter burden for the description to bear, so the baseline of 4 applies; there is nothing meaningful to add about parameter meaning.

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?

The description clearly states the resource — workspace setup status — and enumerates the specific components it covers: people, audiences, templates, landing pages, verified domains, mailbox tenants, simulation delivery, and programme running. It is not a tautology and gives the agent a concrete sense of what the tool reports, though it does not explicitly name or differentiate sibling tools.

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 explicit use cases: 'Use it to answer "are we ready to run a simulation" or to explain why a report is empty.' This tells the agent when the tool is appropriate, but it does not mention when to prefer a sibling such as get_programme_status or get_program_summary, so it lacks explicit exclusions.

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