setup_config

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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds the content of what is produced (v4 setup, OKLCH tokens, theme scripts), which is useful context, but says nothing about whether files are written, output format, or how defaults are applied. A 3 is appropriate with annotations carrying the safety burden.

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?

A single efficient sentence that front-loads the stage and the aliased tool before the output description. Nothing is wasted, though the bracketed stage label is somewhat meta rather than informational.

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?

With 7 optional parameters fully documented in the schema and annotations covering safety, the description only needs to convey purpose and usage. It conveys purpose and output content but omits when-to-use guidance and any note on how the returned setup should be consumed, leaving a modest gap for a setup/config tool with no output schema.

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 100%, with clear enum explanations (framework, stylePack with aesthetic descriptions, environment) and default notes. The description adds no parameter guidance, so this sits at the baseline 3 where the schema does all the heavy lifting.

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 specific verb ("Generate") and concrete outputs (Tailwind CSS v4 setup, OKLCH tokens, theme scripts), and self-identifies as the "Alias of basecoat_setup_config," which resolves the duplication with that sibling. The "STAGE 1: ARCHITECT" prefix further situates it. It is clear what the tool does, though the alias framing leaves the relationship to basecoat_setup_config slightly ambiguous rather than fully distinguishing the two.

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?

The "STAGE 1: ARCHITECT" label implies this is a first-step setup call, but there is no explicit statement of when to use this tool versus the canonical basecoat_setup_config, nor any prerequisites or exclusions. Usage is only inferred from the stage tag and alias note.

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