Register Dasha-Change Webhook

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

Annotations set openWorldHint=true, but the description adds no behavioral context beyond the event trigger. It fails to disclose registration side effects, authentication requirements, or what happens on success/failure. With annotations present, the bar is lowered, but the description still lacks sufficient behavioral detail.

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 brief and includes a group tag and example, which is efficient. However, the example could be more integrated, and some redundant phrasing ('Fires on') could be tightened.

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?

The description lacks critical context: no output schema, no mention of response structure, error handling, or prerequisites. For a webhook registration tool, this is incomplete and may lead to incorrect usage.

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 sole parameter 'url' has 0% schema description coverage, and the description only shows an example request body without explaining the parameter's purpose or constraints. The schema already defines format and maxLength, so the description adds negligible value.

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 tool fires on Vedic Vimshottari dasha period transitions, which distinguishes it from other webhook tools (e.g., webhooks_eclipse_alert, webhooks_mahadasha_end). The purpose 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?

No guidance is provided on when to use this tool versus alternative webhook registration tools. The description does not explain scenarios or exclusions, leaving the agent to guess based on the tool name alone.

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