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 conceptual context (what a blind house means, that remedies follow) but says nothing about computation behavior, cost implications beyond the metadata line, or response shape. This is adequate but not rich; a 3 fits against annotations carrying the safety burden.

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?

The definition is front-loaded, compact, and the bracketed metadata block cleanly separates endpoint/cost/required-args from the conceptual description. Every sentence carries information, though the required-field line is redundant with the schema.

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. The conceptual base is present, but with 33% schema coverage and no usage guidance for a tool that sits among many similar Lal Kitab siblings, the description leaves meaningful selection and parameter gaps.

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 only 33% (15 params), so the description should compensate for undocumented parameters. Instead it merely restates the four required fields (date, time, latitude, longitude) that the schema already enforces as required, adding no syntax or semantic meaning for the remaining 11 optional parameters.

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 defines the specific astrological concept ("Houses with no planet AND no Parashari aspect") that this tool computes, which is clear and non-tautological. However, it never distinguishes itself from close siblings like astroway_vedic_lal_kitab_sleeping_house or astroway_vedic_lal_kitab_remedies, leaving an agent to infer the boundary.

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. The statement that remedies are "essential" is interpretive color, not routing information that would help an agent choose this tool over lal_kitab_remedies or lal_kitab_full.

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