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 the computation's inputs and outputs, and 'Calculate' implies a pure, side-effect-free computation, but it never explicitly states that nothing is mutated, whether it is deterministic, or any auth/permission needs. Adequate but not rich behavioral disclosure.

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?

Cleanly organized with WHEN TO USE / WHAT IT DOES / RETURNS headers, front-loading the purpose. Every sentence carries substantive information with no filler, and the size fits the tool's complexity.

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 pure calculation tool with an output schema already present, the description covers purpose, usage trigger, computed components, and output shape. The main gap is parameter semantics (defaults, ranges), which is a minor shortfall given the tool's otherwise simple, stateless nature.

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%, so the description must compensate for all four parameters. 'From name and birth date' plus 'radical number (from day)' and 'destiny number (from full date)' loosely map name/day/month/year to their roles, but format, valid ranges, and the meaning of the defaults (day=1, name='', year=2000, month=1) are never explained.

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 (full numerology profile from name and birth date), and names the exact techniques involved: Chaldean name numerology, radical number from day, destiny number from full date. The domain is clearly distinct from every sibling, which are all Vedic astrology tools (dashas, vargas, transits), so an agent can route to it unambiguously.

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 clear triggering condition: when the agent needs Chaldean name numerology plus DOB-based radical/destiny numbers with life-aspect scores. It does not name alternatives or state when NOT to use it (e.g., vs. calculate_birth_chart for astrology), but the context is explicit enough to select the tool.

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