upsertWebhookConfiguration

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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'Create or update,' which signals mutation but does not explain upsert/overwrite semantics, idempotency, authentication requirements, validation behavior, or what happens to an existing configuration.

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 one short, front-loaded sentence with no filler. It is concise and scannable, though its brevity comes at the cost of behavioral and contextual detail.

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 mutation tool with no annotations, no output schema, and six parameters, this description is too thin. It omits important context such as owner_email's API-key-dependent requirement, webhook_secret purpose, is_enabled behavior, and expected return value.

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 about 67%, and the description adds only a light mapping of the resource to 'agent + event.' It does not clarify is_enabled, webhook_secret, or the conditions around owner_email, so it adds some value but does not fully compensate for the undocumented parameters.

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 uses a specific verb ('Create or update') and names the resource ('webhook configuration for an agent + event'), making the tool's function clear. It is implicitly distinguished from the sibling read-only tool listWebhookConfigurations, though it does not explicitly name that distinction.

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 this tool is used when a webhook configuration needs to be created or updated, but it gives no explicit when-to-use versus alternatives, no prerequisites, and no guidance about the user/system API key distinction referenced in the schema.

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