B3/5.0

Behavior3/5

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds useful operational facts (POST endpoint, 10 credits Tier 1), but omits the 1-credit precomputed-chart path documented only in the schema and does not mention the default output format is json despite the SVG title.

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?

Two sentences front-load the layout definition, followed by short tagged metadata lines. It is lean, though the group/endpoint/cost tags are boilerplate that could live in structured fields.

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 values need not be described, and annotations cover safety. Still, for a tool with a two-branch body union and a json default that contradicts the SVG title, the description leaves real gaps about which input mode to use and what output to expect.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage at the top level is 0% for a single body parameter that is a union of two large input shapes. The description says nothing about natal vs outer, crossAspects, outerLabel, or which branch to choose, so an agent must dig into the nested schema with no orientation from the description.

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?

The description states a specific visual structure: two concentric wheels, inner natal and outer ring with transit (or progression) planets, plus 'standard bi-wheel layout'. That is enough to tell it apart from a single wheel or a tri-wheel, though it never names the sibling tools it is not.

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

Usage Guidelines2/5

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

No when-to-use guidance is offered: nothing says when a bi-wheel beats astroway_render_wheel_western, astroway_render_tri_wheel, or a composite. It also does not explain that transits vs progressions in the outer ring depend on the data supplied, nor when to pass birth data versus precomputed charts.

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