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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds value by disclosing the return payload (settings, plan-allowed models, per-model credit cost), which matters since there is no output schema. It omits whether any auth/plan constraints affect what is returned.

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?

Two short sentences with no filler; the primary capability (current settings plus plan models and credit cost) is front-loaded and the workflow hint follows.

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 single-parameter read tool with full schema coverage and read-only annotations, the description supplies the essential return-content and sequencing context. It could be marginally more complete about what 'settings' includes, but nothing critical for correct invocation 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 description coverage is 100% and the sole chatbot_id parameter is already documented with its origin (from list_chatbots). The description adds no parameter-level detail beyond the schema, 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 (Get) and resource (a chatbot's current settings), and enumerates what the response contains: models allowed on the plan and credit cost per model. This clearly distinguishes it from the sibling list_chatbots and from update_chatbot_settings.

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?

"Read this before changing settings" gives an explicit sequencing rule that ties the tool to the update_chatbot_settings workflow, which is genuinely useful context. It stops short of naming alternatives or stating when-not to use it, so not a full 5.

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