Changes observed during successful MCP inspections.
v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden, and it does useful work: it signals a read-only diagnostic by enumerating observable state rather than actions, and discloses that the token is reported in masked form, which is non-obvious behavior. It does not explicitly state that it performs no mutations, but nothing suggests side effects and the output schema covers the response shape.
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?
A single dense sentence with the action front-loaded and five enumerated checks in a compact list. No filler, no repetition of the tool name, nothing to trim.
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?
Zero parameters, an output schema present to describe return values, and no annotations to compensate for. The description adequately covers what the tool inspects. A sentence on when it is warranted (e.g., first call in a session) would make it fully complete.
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 tool takes zero parameters, so the baseline is 4. The description correctly adds no parameter discussion, and the empty schema is consistent with the free-form diagnostic framing.
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 (verify) plus a concrete set of resources it inspects: API authentication, account id, token state, zone mapping, and reachable capabilities. Clearly distinguishable from the sibling tools, which are all resource-specific operations. It stops just short of 5 because 'verify' is a slightly soft verb for what is essentially a diagnostic read.
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 implied rather than stated: an agent can infer this is a preflight/diagnostic check to run before other Cloudflare calls or when auth/account questions arise. There is no explicit when-to-use, when-not-to-use, or named alternative among the siblings. Adequate but leaves the routing decision to inference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
