create_webhook

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

No annotations are present, so the description carries the full burden. It mentions the secret key is for signature verification and events to subscribe to, which gives some context, but it does not disclose side effects, required authentication, idempotency, rate limits, or what happens on success or duplicate creation. For a mutating create tool, 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?

The description is a single sentence that is front-loaded with the core purpose, followed by required elements and examples. It contains no unnecessary words or repetition, earning a perfect score for conciseness.

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 straightforward create tool with 5 fully documented required parameters and no output schema, the description is mostly complete. It provides the essential purpose and key inputs, but it lacks any mention of expected response, errors, or duplicate handling. Given the simplicity, this is adequate but not exhaustive.

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 all five parameters are documented in the schema. The description adds a little extra context (e.g., 'secret key for signature verification') but largely rephrases the schema. Baseline of 3 is appropriate as the 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?

Description clearly states the action ('Create a new webhook') and the resource ('for a GitFlic project'), distinguishing it from sibling tools like update_webhook, delete_webhook, and list_webhooks. The verb+resource construction is specific and unambiguous.

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 use for setting up a new webhook subscription but does not explicitly say when to use it versus alternatives or provide any when-not guidance. The context is clear from the sibling list, but the description itself lacks explicit usage guidelines.

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