Behavior2/5

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

No annotations are provided, and the description does not disclose side effects, read-only nature, or any limitations. The mention of auto-payment in USDC hints at cost but does not clarify the tool's operational behavior (e.g., mutability).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with a list of keywords and synonyms, which is redundant and not concise. The core sentence is clear, but the overall structure is messy with extra information (price).

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description fails to specify what the agent should expect as output (e.g., numeric values, chart, etc.). It also lacks details on constraints like date validity, timezone handling, or payment mechanics beyond a vague note on price.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already provides full coverage for the two parameters with date format descriptions. The description adds no additional semantic meaning beyond restating the purpose, meeting the baseline expectation for high coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it computes personal biorhythm cycles from birth date to target date, specifying the three cycles. It is specific and distinguishable from sibling tools like bazi or almanac. The inclusion of synonyms is extraneous but does not obscure the core purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool over other similar tools (e.g., bazi or almanac). It lacks any context on prerequisites, appropriate scenarios, or cases where it should not be used.

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