Life-area timing: children

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), yet the description adds real mechanism: windows are cut at every Vimshottari period change and every Jupiter/Saturn sign change, and each window carries score, components and per-rule basis/source. It also disclaims a domain (no medical/fertility claim), which is a behavioral constraint not encoded anywhere else, though the trailing 'Double transit (K.N.' is cut off and leaves a claim unfinished.

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?

Dense but front-loaded: the astrological basis comes first, then span mechanics, then output shape, with parameters in backticks for scannability. It loses a point for the truncated final clause 'Double transit (K.N.' which is dead weight as written.

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?

With an output schema present, the description needn't explain return values, and it correctly spends its words on method, defaults and scope disclaimers instead. The only real gaps are the unfinished 'Double transit' sentence and the absence of any pointer to when this versus the all-areas variant is appropriate.

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 100%, so years, fromDate, level, kp and minScore are already documented. The description restates the years default and the level default/alternative without adding format or interaction detail beyond the schema, so this lands at the baseline rather than above it.

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 names the exact resource (timing windows for children), the astrological basis (5th house, its lord, Jupiter as putra karaka, 9th supporting, KP group 2/5/11), and the period system used. An agent can tell this is the children life-area timing tool rather than the career, marriage or all-areas sibling without opening the schema.

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?

Usage is implied by the life-area label and the explicit scope boundary 'No medical or fertility claim', but there is no statement of when to prefer this over astroway_vedic_timing_all or the other timing_* siblings, and no prerequisites such as the credit cost (50 credits, Tier 3) being surfaced.

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