Check whether new suggestions can be generated for a group

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

With readOnlyHint and openWorldHint already declared, the description adds meaningful value by stating it schedules nothing and returns an explanation when unavailable — the key behavioral trait for a check tool. It does not cover rate limits or latency, so it falls 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?

One dense sentence that front-loads the answer (whether a run would be scheduled) and closes with the key differentiator vs. generate_prompt_suggestions. Nearly no waste, though the em-dash aside makes it slightly heavy for a mobile read.

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?

An output schema exists, so return structure needn't be described; the description still usefully explains the semantic of the return (availability plus the reason when not). For a one-parameter read-only check, nothing an agent needs 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 the single groupId parameter is fully documented in-schema, so baseline is 3. The description adds only the scoping phrase 'of the active project,' no new format or constraint details beyond 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?

The description names a concrete operation — a pre-flight availability check for generate_prompt_suggestions on one prompt group — and explicitly distinguishes itself from that sibling by noting it performs the same check 'without scheduling anything.' An agent can select it correctly without opening either schema.

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?

It clearly frames the use case: determine whether generate_prompt_suggestions would schedule a run right now and, if not, why. The alternative (calling generate_prompt_suggestions itself) is named, giving strong implied routing, though it never states an explicit call-order rule like 'run this before generating.'

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