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

Annotations already declare readOnlyHint=true, so the read-only safety profile is known. The description adds value beyond that by disclosing the return payload (settings plus full knowledge text) and by explaining the editing workflow this tool is meant to support. It doesn't need to restate the annotation, and it doesn't contradict it.

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 sentences, both high-value. The purpose is front-loaded in the first sentence, and the critical workflow caveat about configure_chatbot is in the second. No filler or repetition.

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 simple one-parameter read tool with a readOnly annotation, this description is complete. It tells the agent what the tool returns, when to call it, and how it relates to the sibling configure_chatbot. There is no output schema, but the description sufficiently covers the essential return information.

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 schema covers 100% of parameter documentation: projectId is described as 'The project's ID.' The description adds no further parameter-specific detail, but with complete schema coverage the baseline of 3 is appropriate.

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 states a specific verb and resource: 'returns the settings AND the full knowledge text.' It also explicitly names the sibling tool configure_chatbot, making the distinction clear. An agent can tell this is the read/precursor tool, not the mutation tool.

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 opening 'EDITING A BOT? Call this FIRST' gives an explicit, conditional usage rule. It also explains why: configure_chatbot REPLACES the knowledge string with no merge, so the returned text must be edited and sent back in full. This is strong when-to-use and alternative-selection guidance.

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