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

Annotations already declare this is a non-destructive, closed-world write. The description adds genuinely useful behavior beyond that: the secret is auto-generated and shown only once, and the response includes provider-specific setup instructions. It omits what happens on a duplicate-provider 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?

Four short sentences with zero filler; the create action, side effects, and the one-per-provider constraint are all front-loaded and each sentence carries distinct information.

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 no output schema, the description responsibly covers return contents (secret shown once, URL, setup instructions). The only gap is unspecified behavior when a provider integration already exists, which matters given the stated uniqueness constraint.

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%, so parameters are already documented by the schema. The description only adds the provider-default hint implicitly and says nothing extra about project_id or the context analytics parameter, 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?

States a specific verb and resource ('Create a deploy-provider webhook integration for a project') and is clearly distinguishable from siblings like list_deploy_integrations, delete_deploy_integration, and test_deploy_integration.

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 'One integration per provider per project' line gives a prerequisite constraint, but the description never says when to choose this versus list/test/delete siblings, nor what to do if an integration already exists. Usage is implied rather than guided.

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