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 fully covered. The description adds only that the list is a fixed set of 40 works; it says nothing about output format, ordering, or stability of the ids. Adequate but thin on top of 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?

A single front-loaded sentence: verb, count, resource, and the qualifying condition, followed by a compact illustrative list. Every clause earns its place and nothing is padded.

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 no parameters, no output schema, and full annotation coverage, the description carries almost the whole burden and does so for purpose and content. The remaining gap is that it does not tell the agent how the returned karma ids are consumed by the sibling muhurat tools, which would close the loop.

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 tool takes zero parameters, so per the rubric the baseline is 4. There is nothing for the description to clarify about inputs, and it correctly does not invent any.

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?

States a specific verb ('List') and resource ('40 works (karma ids)') plus the exact condition that makes them useful — a personal Shubh Muhurat can be calculated for each. Concrete examples (marriage, griha pravesh, vehicle purchase) make the resource unambiguous and implicitly separate it from the sibling computation tools shubh_muhurat and vivah_muhurat.

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?

The description implies this is the enumeration step that feeds shubh_muhurat, but it never states when to call it, that it should be called before requesting a muhurat, or what to do with the returned ids. No alternatives or exclusions are named, so the agent must infer the workflow.

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