get_group_replication_status

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

The description adds valuable context beyond annotations by specifying the analysis scope (membership, roles, channels, etc.) and the MySQL Group Replication requirement. Annotations already cover safety (readOnlyHint=true, destructiveHint=false), so the bar is lower, but the description provides useful operational context without contradicting annotations.

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 efficiently structured: the first sentence states the core purpose, followed by a bulleted list of analysis areas, and ends with a critical usage constraint. Every sentence earns its place with no wasted words, making it easy to scan and understand.

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 parameterless tool with rich annotations (readOnlyHint, idempotentHint) but no output schema, the description provides good context on what it analyzes and when to use it. It could slightly improve by hinting at the return format (e.g., structured data vs. raw text), but it's largely complete given the tool's complexity.

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?

With 0 parameters and 100% schema description coverage, the baseline is 4. The description doesn't need to explain parameters, but it implicitly confirms no inputs are required by focusing on the analysis output, which is appropriate for this parameterless tool.

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 specific action ('Get MySQL Group Replication status') and resource ('MySQL Group Replication'), distinguishing it from siblings like 'get_replication_status' (which likely covers standard replication) and 'get_galera_status' (a different clustering technology). The detailed analysis scope further clarifies its unique focus.

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 explicitly states when to use this tool ('Only applicable to MySQL with Group Replication enabled'), providing clear context for its application. This distinguishes it from alternatives like general replication or Galera tools, though it doesn't name specific siblings as alternatives.

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