Challenge Cycles (chaldean)

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, covering safety and idempotency. The description adds 'life-area difficulties to master' but does not fill gaps such as output structure, rate limits, or authentication needs. With annotations present, score is baseline adequate.

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 with purpose in two sentences, plus a group label and example. Every element earns its place with no redundancy or fluff.

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?

For a tool that calculates four Challenge cycles without an output schema, the description could explain what the four challenges are or hint at return values. It covers the basic purpose but lacks detail for full understanding.

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 coverage is 100% with all four parameters described. The description offers an example request (date, name) but adds no semantic meaning beyond the schema. Baseline 3 applies as 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?

The description clearly states the tool calculates four Challenge cycles derived from birth date components in the Chaldean system, distinguishing itself from sibling tools like numerology_chaldean_life_path or numerology_chaldean_pinnacles by specifying 'life-area difficulties to master'.

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 provides no guidance on when to use this tool versus alternatives like numerology_chaldean_balance or numerology_chaldean_maturity. It lacks explicit when-to-use or when-not-to-use context, and the example request body only serves as parameter format illustration.

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