Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description specifies 'deterministic' and 'No AI,' but lacks details on side effects, authorization needs, or what happens if required parameters like name are missing (name is not required in schema but needed for some outputs). No annotations are provided.
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 a single, well-structured sentence that front-loads the purpose and lists key outputs efficiently. It avoids superfluous information.
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?
Despite listing output components, the description lacks details on return format, parameter constraints (e.g., required name for full profile), and context for targetYear. No output schema exists to compensate, leaving gaps for an AI agent.
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?
With 0% schema description coverage, the description adds no parameter-level details. It does not explain the meaning or constraints of each parameter, such as name format or targetYear's role in Personal Year calculation.
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 it provides a 'Full deterministic Pythagorean numerology profile' from name and birth date, listing specific outputs like Life Path, Expression/Destiny, and Personal Year. It distinguishes from siblings by implying a comprehensive profile vs single-number tools like life_path or name_numbers.
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 implies use for full profile computation but does not explicitly state when to use this tool over siblings like compatibility, life_path, or name_numbers. No guidance on prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool targets a distinct numerology aspect: compatibility between life path numbers, core life path number from birth date, name-derived numbers, and a full profile combining both. No two tools serve identical purposes despite some overlap in outputs.
All tool names are noun phrases with underscores, following a pattern of [domain]_[specific] (e.g., life_path, name_numbers). 'compatibility' is a single noun but fits the naming convention used. Consistent and predictable.
4 tools cover the essential numerology operations: getting a life path, name numbers, a full profile, and compatibility. The count is appropriate for the domain without being overwhelming or sparse.
The tools provide comprehensive coverage of standard Pythagorean numerology: life path, expression, soul urge, personality, birthday, maturity, personal year, and compatibility. The full profile tool aggregates most values, and the others provide specific subsets. No major gaps for typical numerology queries.
