create_github_webhook

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses little: it does not state required token scopes/permissions, whether the call is idempotent when the webhook already exists, whether the secret is used for HMAC verification, or what an error/success looks like. 'Push webhook' is the only real behavioral detail added beyond the name.

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?

A single well-formed sentence with the action front-loaded and no filler. It is efficient, though the space saved could have been used for the missing prerequisites and auth notes.

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 5-parameter mutation tool with no annotations and no output schema, the description should explain token/precondition requirements, idempotency, and what is returned or registered. None of that is covered, leaving the agent to guess about a state-changing GitHub operation.

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 every parameter (repo, owner, secret, webhook_url, github_token) is already documented, which sets the baseline at 3. The description adds no further meaning about parameter roles beyond implying webhook_url is the cPanel deployment endpoint.

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 gives a specific verb and resource ('Create a push webhook on a GitHub repository') plus the downstream intent (trigger redeployment on cPanel), so the agent knows exactly what operation is performed. It does not differentiate itself from nearby siblings such as connect_github_repo, redeploy_from_github, or generate_github_actions_workflow, which also touch GitHub-to-cPanel deployment.

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?

There is an implicit rationale for using it (enabling automatic redeploy on push), but no explicit when-to-use vs. when-not guidance and no mention of alternatives among the many GitHub/deployment siblings. Prerequisites, such as whether a GitHub token must already be configured via configure_github_token or supplied per-call, are left unstated.

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