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

No annotations are provided, so the description carries the full burden. It discloses that the tool computes the chart and returns deterministic recommendations, which is helpful, but says nothing about permissions, side effects, rate limits, or whether output is purely advisory.

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 description is front-loaded and broken into WHEN TO USE, WHAT IT DOES, and RETURNS sections. Every sentence adds concrete information without redundant restatement.

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?

Because a full output schema exists, the description need not enumerate return values, though RETURN text is still useful. The major gap is parameter semantics at 8 params with zero schema descriptions and no annotation coverage, which makes the definition under-informative for invocation details.

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 0% for 8 parameters, so the description must compensate. It only implies birth details are needed and does not explain required fields, formats, timezone_offset, or the defaults for latitude, longitude, minute, or timezone.

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 and resource: recommend Vedic remedies from a birth chart. It clearly distinguishes itself from calculation siblings by being prescriptive rather than analytical, but it does not name siblings like ask_cosmic_advisor that could also be used for remedial advice.

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 WHEN TO USE section gives a concrete condition: user asking about remedies for planetary afflictions or life challenges with birth details available. It does not state when not to use it or name explicit alternatives such as calculate_birth_chart or ask_cosmic_advisor.

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