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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description contributes cost (20 credits, Tier 2) and group, which is real value not present in the structured fields, but says nothing about what the cascade returns or its ordering.

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 short lines, front-loaded with the tool's identity before the metadata tags. Nothing is wasted, though the terseness borders on under-specification rather than true economy.

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?

With a full input schema and an output schema present, the description need not explain return values, and cost/group are supplied. However, for a member of a very dense sibling family it still omits what the 4-level cascade yields and how it relates to the other shatabdika levels, leaving the agent to infer.

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% and the birth-data block is thoroughly documented in the schema itself (formats, ayanamsa, timezone rules, houseSystem letters). The description adds no parameter meaning, which is the correct baseline when 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?

Names a specific resource (Shatabdika Sookshma dasha) and adds '4-level cascade', which indicates the nesting depth and hints at the distinction from the flatter sibling levels (maha/antar/pratyantar/prana). It lacks a verb and never explicitly contrasts itself with the ten-plus other dasha tools, but the resource is clear enough to act on.

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 when-to-use guidance, no prerequisites, and no named alternative. An agent choosing among shatabdika_maha/antar/pratyantar/prana/sookshma gets only the implicit hint of '4-level cascade' to go on, which is not sufficient routing guidance.

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