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

With no annotations provided, the description carries the full burden of behavioral disclosure. It implies a mutation ('Updates'), but fails to specify required permissions, whether changes are reversible, rate limits, or the response format. This is a significant gap for a mutation tool, as the agent lacks critical operational 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, efficient sentence with no wasted words. It is front-loaded and directly states the action, making it easy to parse quickly. Every word serves a purpose, adhering to ideal conciseness standards.

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 tool's complexity as a mutation operation with no annotations, no output schema, and 0 parameters, the description is incomplete. It does not explain what 'Updates' entails, the expected outcome, or any side effects. For a tool that modifies configurations, this lack of detail leaves the agent underinformed about its behavior and implications.

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?

The tool has 0 parameters with 100% schema description coverage, so the schema fully documents the absence of inputs. The description mentions `<WEBHOOK_NAME>` as part of the endpoint, but since no parameters exist, this is likely embedded in the tool path or context. The description adds minimal value beyond the schema, but with zero parameters, a baseline of 4 is appropriate as no compensation is needed.

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 'Updates the endpoint with the name `<WEBHOOK_NAME>`' states a vague purpose: it specifies the verb 'Updates' and the resource 'endpoint', but lacks clarity on what exactly is being updated (e.g., configuration, settings, status) and what an 'endpoint' refers to in this context. It does not distinguish from siblings like 'create_integration_webhooks_configuration_webhooks' or 'delete_integration_webhooks_configuration_webhook', leaving ambiguity about its specific role.

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. The description does not mention prerequisites (e.g., existing webhook), exclusions, or compare it to sibling tools such as create or delete operations for webhooks. This absence leaves the agent without context for appropriate tool selection.

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