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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description usefully adds the credit cost (20 credits, Tier 2), which an agent cannot get from annotations or schema, but says nothing about compute cost, latency, or the shape of the cascade.

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?

Extremely short and front-loaded: the resource, cascade depth, group and cost are all stated without filler. The brevity is a virtue structurally even though the content is thin.

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?

An output schema exists, so return values need not be explained. But with roughly fifty sibling dasha tools and five Ashtottari levels, an agent needs to know what a sookshma subdivision is and why to pick this level over antar/pratyantar/prana; the description supplies none of that.

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 nested birth-data schema is thoroughly documented (date/time formats, timezone handling, houseSystem letters, field projection). The description adds nothing beyond that, so the baseline 3 applies; '4-level cascade' only loosely gestures at output depth.

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 names the specific dasha system and subdivision (Ashtottari Sookshma) and adds that it is a '4-level cascade', which conveys the output's structure. However, it is largely a restatement of the title and gives no basis for distinguishing this from the four sibling Ashtottari levels (maha, antar, pratyantar, prana) or from the other nine dasha systems' sookshma 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, no prerequisites, and no reference to the closely related antar/pratyantar/prana/maha siblings. The only routing signal is the [Group: Vedic] tag, which every sibling shares.

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