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's one value-add is the cost disclosure (10 credits, Tier 1), which annotations do not carry. It says nothing about permissions, limits, or what the four cycles contain beyond 'age boundaries'.

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?

Front-loaded with the verb and output shape in the first clause, and the group/cost metadata is compact. No filler, though the metadata tags occupy space that could have carried usage or parameter guidance.

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, and cost is disclosed. However, for a 2-required-parameter tool with 50% schema coverage, the definition leaves the agent without guidance on name spelling/format conventions or how the four cycles are scoped.

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 50%: only `fields` and `precision` are documented in the schema, while the two required parameters (`name`, `date`) have no description anywhere. The description adds no meaning to any parameter and does not compensate for the undocumented name/date semantics (e.g., which name form numerology expects).

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 ("Calculate") and resource ("four Pinnacle cycles with their age boundaries"), plus a gloss ("life chapters of opportunity"). The [Group: Numerology: Vedic] tag separates it from the Chaldean/Kabbalistic/Pythagorean pinnacles siblings, though the description never explicitly names an alternative.

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 or when-not-to-use guidance. The group tag implies this is the Vedic variant of the pinnacles family, but nothing tells the agent when to pick pinnacles over life_path, challenge, or maturity, nor any prerequisite for the request.

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