cloudflare_check

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

With no annotations, the description carries the full burden. It does list expected return outputs, which adds value, but it does not explicitly state that the operation is read-only, nor does it cover error behavior, rate limits, or permission requirements beyond the schema. The tool name 'check' implies non-destructive behavior, but an explicit statement would be stronger for a no-annotation context.

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 a single, front-loaded sentence that names the action and resource, then lists return items. Every word carries weight; there is no fluff or repetition. This is exemplary conciseness.

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 check tool with three well-documented parameters and no output schema, the description adequately explains the return value categories and recommendations. However, it could be more complete by explicitly noting the read-only nature and when to pair it with cloudflare_fix. The overall structure is solid, but minor gaps prevent a perfect score.

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 schema already documents each parameter (email, api_key, zone_id) clearly. The description adds no further semantic meaning to the parameters, so the baseline score 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 clearly states the tool checks CloudFlare security and performance settings for a zone, listing specific return items (SSL mode, TLS version, HSTS status, bot protection). This is specific and understandable, but it does not explicitly distinguish itself from the sibling tool cloudflare_fix, so it misses the top score.

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?

No guidance is provided on when to use this tool versus alternatives like cloudflare_fix. The description does not mention exclusions, prerequisites, or scenarios where another tool would be more appropriate. This leaves the agent without decision support.

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