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

Annotations already declare readOnly, idempotent, closed-world and non-destructive behavior, so the safety profile is covered. Beyond that the description adds only cost (10 credits, Tier 1) and a group label; it says nothing about what inputs are needed, what the result contains, or any limits, which is thin for a read tool that appears to run a full astrological computation.

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?

One short front-loaded sentence plus two metadata tags; nothing is padded and nothing is buried. It is terse rather than wasteful, but the brevity comes at the cost of under-specification.

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?

An output schema exists, so return values need not be described. Nevertheless, for a 15-parameter calculation tool with 33% schema coverage and no usage or behavioral guidance, the definition omits how to supply the required natal-style inputs and when this result is the right one to request.

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 only 33%, and the four required parameters (date, time, latitude, longitude) carry no prose meaning in either the schema or the description. The description contributes zero parameter semantics, so it fails to compensate for the coverage gap across 15 parameters.

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 output (element-based risk tolerance plus recommended safeguards), so an agent knows roughly what it will get back. However, it is a noun phrase with no verb and no differentiation from the very similar sibling astroway_financial_risk_tolerance, leaving the business-vs-financial distinction to inference from the tool name alone.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as astroway_financial_risk_tolerance or astroway_business_founding_chart. The '[Group: Business Astrology]' tag is a categorization label, not usage direction.

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