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

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly explains that this tool returns a configuration snippet rather than performing the configuration directly, which is valuable behavioral context. It also mentions the need to restart the server afterward. However, it doesn't disclose potential authentication requirements beyond credentials, rate limits, or error behaviors.

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 perfectly concise with two sentences that each serve a clear purpose: the first establishes the context and action, the second explains the outcome and next steps. There's zero wasted language, and it's front-loaded with the essential information about when and why to use the tool.

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 configuration tool with no annotations and no output schema, the description provides good context about the tool's purpose and usage flow. It explains what happens (returns configuration snippet) and what needs to happen next (restart server). However, it doesn't describe the format of the returned snippet or potential error conditions, leaving some gaps in completeness.

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 description coverage is 100%, so the schema already documents all four parameters thoroughly. The description doesn't add any additional parameter semantics beyond what's in the schema descriptions. It mentions 'credentials' generally but doesn't elaborate on specific parameters. This meets the baseline expectation when schema coverage is complete.

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: 'Call this tool with your CleverTap credentials and it will return the exact configuration snippet to paste into your MCP settings.' It explicitly addresses the initial setup scenario ('no project configured yet') and distinguishes this as a one-time configuration tool. The verb 'configure' is specific and the resource is the CleverTap MCP project setup.

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 provides explicit guidance on when to use this tool: 'CleverTap MCP has no project configured yet.' It also specifies the follow-up action required: 'then restart the server to activate all tools.' Since there are no sibling tools mentioned, the description appropriately focuses on the specific use case without needing to differentiate from alternatives.

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