cloudflare_tunnel_config_update

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

With no annotations, the description must convey behavioral traits. It only says 'update' without disclosing that the entire config is replaced, potential side effects (e.g., tunnel reload), authentication needs, or error conditions. This is insufficient for safe invocation.

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 sentence with no redundancy. However, it is too brief, sacrificing useful details that could be included concisely.

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?

Given the complexity (nested object, no output schema), the description is insufficient. It does not explain that the update is a full replacement, the format of tunnel_id, or possible errors, making it incomplete for an agent to use reliably.

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 coverage is 100% with detailed parameter descriptions for the nested config object, including the catch-all rule requirement. The description adds no extra meaning beyond the schema, thus baseline score of 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?

The description states a specific verb ('update') and resource ('ingress configuration for a Cloudflare Tunnel'), distinguishing it from related sibling tools like cloudflare_tunnel_config_get (retrieve) and cloudflare_tunnel_create (create). However, it does not specify that the update replaces the entire configuration, which is important for clarity.

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 (e.g., getting the config first, then modifying). Prerequisites (e.g., tunnel must exist) or exclusions are not mentioned, leaving the agent without contextual direction.

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