Western Wheel (SVG)

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

Annotations already state readOnlyHint=true, destructiveHint=false, idempotentHint=true. Description adds 'Pure server-side, no browser needed' which is minor additional context. Does not contradict annotations. No discussion of performance or side effects beyond annotations.

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?

Highly efficient: two sentences, one group label, one example. Every element adds value. Front-loaded with core purpose.

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?

Given complex nested schema and no output schema, description could detail output format (SVG vs JSON) or visual characteristics. Example shows format option but doesn't explain what the SVG contains beyond the initial list. Adequate but not comprehensive.

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 coverage is 100%, and schema includes descriptions. Description provides a full example request body showing common parameters, which helps clarify usage. However, no additional semantic details beyond schema.

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?

Clear verb 'Render' and specific resource 'Western natal wheel as SVG'. Names components (signs ring, houses ring, planets, aspect lines). Distinguishes from sibling render tools like render_wheel_vedic_east by explicit 'Western' in name and title.

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?

No explicit when-to-use or when-not-to-use compared to alternatives. The name and group 'Visualization' imply use for Western charts, but no contrast with other wheel renderers. Missing guidance on choosing between this and other visualization tools.

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