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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety bar is low. The description's genuine addition is the assurance that the stored token is never revealed, which is real behavioral context beyond the annotations; the closed-world sentence largely restates openWorldHint=false.

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, front-loaded with purpose, with no padding. The 'Safety: Closed-world...' clause partially duplicates the openWorldHint=false annotation, which costs a little.

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?

With an output schema present, rich annotations, no required parameters, and full schema coverage, the description only needs to state scope and any safety caveat — both are present. Do not need to discuss return format.

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 single optional parameter is fully documented in the schema (100% coverage), including the 'when true and authenticated' condition. The description adds no further meaning about it, so 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?

Names a specific verb ('Inspect') and resource ('Tripsy MCP configuration and authentication state'), which is clearly separable from the CRUD siblings. It does not explicitly name the nearest sibling (tripsy_me_show) as an alternative, but the configuration/auth-state framing makes the distinction inferable.

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?

Usage is only implied: an agent can infer this is the pre-flight/auth-check tool, reinforced by the parameter note 'when true and authenticated'. There is no explicit when-to-use, when-not-to-use, or named alternative among the ~50 sibling tools.

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