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

The description lists 'delete' as an action, which is destructive, but the annotations set destructiveHint to false. This is a direct contradiction, making the behavioral profile misleading. No additional behavioral context (e.g., persistence details, side effects) is provided to resolve the conflict.

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 two concise sentences with no filler. The first sentence front-loads the action and resource, while the second adds a critical detail about environment-variable references. Every word contributes value.

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 tool with 6 parameters, no output schema, and conflicting annotations, the description is not complete. It lacks parameter-level explanations, action semantics, prerequisites, and return values, and the contradiction with destructiveHint further reduces 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?

With 0% schema description coverage, the description was expected to compensate. It partially explains urlEnvVar and hmacSecretEnvVar by mentioning environment-variable references, but it leaves other parameters (id, kind, enabled, action) without any semantic guidance beyond the enum values.

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 specifies the exact verbs (list, save, delete) and the resource (persistent Codex, desktop, and HMAC HTTPS webhook subscriptions). This clearly distinguishes it from sibling tools focused on credentials, jobs, and policies.

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 implies usage for managing webhook subscriptions and notes the environment-variable reference pattern, but it does not explicitly state when to use this tool over alternatives or provide exclusions. The presence of sibling tools offers context, but the description itself lacks direct guidance.

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