Get the exact calendar date of all 25 baby milestones for a given birth date (monthly, special days, and birthdays), each with days_left and whether it is reached. Use this to add baby milestones to a calendar.
| Name | Required | Description | Default |
|---|---|---|---|
| birthday | Yes | The baby's birth date as YYYY-MM-DD (not in the future). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears the full burden. It discloses the output fields (dates, days_left, reached) and suggests a read operation via 'get', but does not affirmatively state non-destructiveness or other behavioral traits like authentication or rate limits.
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 two sentences, directly stating the function and a suggested use case. Every sentence contributes value, and no extraneous content is present.
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?
The description adequately covers the input and outlines the output (dates, days_left, reached) despite lacking an output schema. It mentions all 25 milestones and the three output fields, making it sufficiently complete for the tool's simplicity.
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?
The input schema has 100% description coverage for the single parameter 'birthday', so the description adds little beyond restating that a birth date is needed. The baseline is 3, and no additional semantic value is provided.
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 retrieves exact calendar dates for 25 baby milestones from a birth date, specifying the data returned (days_left, reached status). This distinguishes it from siblings like get_baby_age and list_milestones.
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 a clear usage hint ('Use this to add baby milestones to a calendar') but does not explicitly mention when not to use it or contrast with sibling tools. Nonetheless, the context implies its specific purpose.
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 serves a distinct purpose: age calculation, milestone dates, zodiac sign, and milestone listing. No overlap in functionality.
All tool names follow a consistent verb_noun pattern with snake_case (get_baby_age, get_milestone_dates, get_zodiac_sign, list_milestones).
Four tools are appropriate for the domain, covering core baby age queries without being excessive or insufficient.
The tool set covers all essential aspects: age calculation, milestone dates, zodiac sign, and a reference list of milestones. No obvious gaps for the stated purpose.
