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

Annotations already signal read-only, idempotent, non-destructive behavior. The description adds useful behavioral context by stating exactly what is returned: a Lal Kitab chart with planet placements rendered as SVG and image. It does not disclose potential limitations, but the annotations cover the safety profile.

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 two short sentences with no filler. It front-loads the core purpose and immediately follows with the output format, making the tool’s behavior easy to grasp at a glance.

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?

Given the rich input schema, read-only annotations, and the stated output format, the description is largely complete for correct invocation. It would benefit from distinguishing this tool from the many sibling chart tools, but the essential call contract—birth details in, Lal Kitab SVG/image out—is clear.

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 description itself adds no parameter-level guidance and does not compensate for the low top-level schema description coverage. However, the nested KundliInput schema provides detailed descriptions and examples for each birth field, so the agent can still resolve parameter meaning from the schema.

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 states a specific verb ('Generate'), a concrete resource ('Lal Kitab horoscope chart'), and the output format ('SVG and image'). It is clearly distinguishable from generic horoscope chart tools because it explicitly names the Lal Kitab style and planet placements.

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 explicit when-to-use or when-not-to-use guidance, and no alternative tools are named. The intended use is implied by the name and description: use this when you need a Lal Kitab-style chart for a birth chart. However, with many sibling chart tools, explicit routing would be valuable.

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