Arroyo: Element Integration

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

Annotations already state readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description usefully adds a billing cost (10 credits, Tier 1) and the transport endpoint, which are real planning facts not present in structured fields, but it says nothing about what the response contains or how the 'strategies' are derived. The POST verb alongside readOnlyHint is transport-only and not a behavioral contradiction.

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 one-line purpose is front-loaded and the bracketed metadata is compact and scannable with no filler. However, brevity here comes at the cost of substance rather than being earned by efficiency.

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. But with 13 parameters at 23% coverage and a very abstract concept ('weak element integration'), the description leaves the agent without enough context to construct a correct call or know what it is asking for. The cost/endpoint block is helpful but insufficient for a tool of this complexity.

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 23% across 13 parameters, so the description must compensate and it does not. Listing 'date, time, latitude, longitude' merely repeats the schema's required array, and the many enum-heavy options (houseSystem, zodiacType, ayanamsa, cosmogram, name/city) are left unexplained.

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 a resource domain ('strategies for integrating weak elements'), which is slightly more informative than the title alone, but it never says what 'weak elements' means, how they are determined, or what the output looks like. Siblings such as astroway_psychological_modern_arroyo_element_balance and _relational_element_map are not differentiated at all, so an agent cannot easily pick between them.

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 indication of when to call this versus the closely related element_balance or relational_element_map tools, and no prerequisites or workflow context. The bracketed metadata only lists required fields and cost, which is not usage guidance.

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