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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds real context — endpoint path and the 20-credit Tier 2 cost — which is useful for a metered API call, but it says nothing about output shape or any rate/limit behavior beyond cost.

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?

It is short and free of padding, but the first line is largely a restatement of the name/title, and the bracketed metadata tags are machine-oriented rather than agent-facing prose. No waste, but also almost no substance.

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 a nested birth-data body, an output schema, and a dense family of near-identical dasha siblings, this description is incomplete: it does not say what a sookshma-level Shoola dasha is, how deep the cascade goes in the response, or when this level is preferred over maha/antar/pratyantar/prana.

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%, including rich notes on timezone, timezoneOffset, coordinates and compact-mode fields/precision, so the schema carries parameter semantics fully. The description adds no parameter information, which is the correct baseline of 3 when the schema already does the work.

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 essentially restates the tool name and title ('Shoola Sookshmadasha'), adding only '4-level cascade'. It never states what the tool returns (Shoola dasha periods at the 4th/sookshma level) or how it differs from the sibling Shoola maha/antar/pratyantar/prana tools.

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 no guidance on when to use this tool versus the many sibling dasha tools, no prerequisites, and no exclusions. An agent has nothing to route on besides the name itself.

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