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

Annotations already declare the safety profile (readOnlyHint=true, idempotentHint=true, destructiveHint=false, openWorldHint=false), so the description only needs to add context. It does add parallel execution and a 100-credit Tier 4 cost, which is useful. However, it omits latency implications from LLM synthesis, auth requirements, and any detail about valid agent choices.

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 text is very short and front-loads the core action before the group and cost tags. No sentence is wasted, though the brevity reflects under-specification rather than thorough contextual completeness.

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?

This is a complex tool with a nested chart object, six parameters, required agent and question fields, and many sibling tools. The description explains almost none of that beyond a two-line summary and cost, leaving significant gaps even though an output schema exists for return values.

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 only 50%, and the description adds no parameter-level meaning for question, agents, chart, fields, language, or precision. In particular, the required 'agents' array and its 2-4 item constraint, as well as how 'chart' relates to the question, are left entirely to 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 gives a high-level verb and resource ('Run N personas in parallel + LLM synthesis') but does not define what a persona is, what is being coordinated, or how this differs from siblings such as astroway_mcp_agent_debate. The [Group] and [Cost] tags are metadata rather than purpose clarification.

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 when-to-use, when-not-to-use, or alternative-tool guidance. The closest sibling, astroway_mcp_agent_debate, is not mentioned, and the cost tier alone does not tell an agent when this tool should be selected.

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