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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description usefully adds the group and cost (20 credits, Tier 2), but says nothing about output shape, cascade depth semantics, or any behavioral nuance beyond the annotations.

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?

Very short and front-loaded, but it is under-specified rather than genuinely concise. The bracketed metadata lines earn their place (cost/group), yet the core sentence leaves the technique's level unclarified given the dense sibling set.

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 and annotations are rich, so return-value and safety detail need not live in the description. Still, for a specialized Vedic technique with many near-identical siblings, the description is thin on how this level relates to the others, leaving selection to the name alone.

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 schema extensively documents date/time/coords/timezone/houseSystem plus the compact-mode fields and precision parameters. The description adds no parameter meaning, so baseline 3 applies since 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 the specific technique ('Tribhagi Sookshmadasha') and adds a structural hint ('4-level cascade'), so the agent knows it is a Vedic dasha computation. However, it does not distinguish this level from its siblings (tribhagi_maha/antar/pratyantar/prana) or clarify what '4-level cascade' means relative to the sookshma level. Essentially restates the title with minimal added meaning.

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 and no mention of alternatives, despite a large family of sibling dasha tools at different levels. The agent must infer from the name alone whether to pick this tool over tribhagi_pratyantar or tribhagi_prana.

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