B3.4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description adds genuinely useful operational context absent from structured fields: an endpoint and a 10-credit Tier 1 cost, which matters for budget-aware agents. It does not say whether the `name` field actually affects the result, which is the most behaviorally surprising aspect of a date-based calculation.

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

Conciseness4/5

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

Front-loaded with the core action and system, followed by scannable bracketed metadata (group, endpoint, required params, cost). Slightly redundant in restating "Required: name, date," which the schema already enforces, but overall tight with no filler prose.

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

Completeness3/5

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

An output schema exists, so return-value detail is not needed, and the cost/endpoint metadata rounds out the operational picture. However, for a tool whose siblings include both a non-strict Kabbalistic life-path and a near-identical long-named twin, the description leaves unclear what "strict" changes and why `name` is mandatory, which are the two facts an agent most needs before calling.

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?

Schema coverage is 50%: `fields` and `precision` are well documented in the schema, but `date` and `name` carry no schema descriptions. The description clarifies that the date is a birth date reduced via year+month+day, which adds real meaning, but it does not state the expected YYYY-MM-DD format explicitly nor explain why a `name` is required for a life-path number.

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?

States a specific verb and resource ("Calculate the Life Path number") plus the exact system variant ("Kabbalistic (Mathers strict)") and the reduction inputs (year + month + day). It distinguishes itself from the Pythagorean/Chaldean/Vedic life-path siblings and from the non-strict Kabbalistic one only by the word "strict," which is never explained, so an agent must infer the difference.

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

Usage Guidelines3/5

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

Usage is only implied by the system label; there is no explicit statement of when to pick this over `astroway_numerology_kabbalistic_life_path` (non-strict) or the Pythagorean/Chaldean counterparts. The alias note tells the agent this is a duplicate entry point, which helps routing, but no exclusions or selection criteria are given.

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