pylon_create_webhook

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

With no annotations provided, the description carries full burden but only states the basic purpose. It doesn't disclose important behavioral traits: whether this requires specific permissions, what happens on duplicate creation, rate limits, authentication needs, error conditions, or what the response contains. For a creation tool with zero annotation coverage, this is a significant gap.

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?

Two sentences with zero waste. First sentence states the core purpose clearly, second provides practical usage context with specific examples. Every word earns its place, and the structure is front-loaded with the main action.

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 creation tool with no annotations and no output schema, the description provides adequate basic purpose but lacks completeness. It doesn't explain what happens after creation, what the return value contains, error handling, or important constraints. The 100% schema coverage helps, but behavioral aspects remain undocumented.

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 the schema already documents all three parameters thoroughly. The description doesn't add any parameter-specific information beyond what's in the schema. It mentions integration examples but doesn't explain parameter relationships or usage nuances. Baseline 3 is appropriate when schema does the heavy lifting.

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 clearly states the specific action ('Create a new webhook') and resource ('webhook'), with explicit purpose ('to automatically notify external systems when events occur in Pylon'). It distinguishes from siblings like pylon_delete_webhook by focusing on creation rather than deletion, and from other create tools by specifying webhook functionality.

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 provides clear context for when to use this tool ('to integrate with Slack, Discord, email systems, or custom applications'), giving practical integration examples. However, it doesn't explicitly state when NOT to use it or mention alternatives like pylon_get_webhooks for viewing existing webhooks, though the sibling list shows related tools.

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