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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It states the tool creates code but does not mention any side effects, such as writing files, modifying the project structure, or requiring specific permissions. It also fails to disclose what happens if the design direction is not approved, or any output format or error behavior. This is a significant gap for a tool that likely produces files.

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 description is a single, efficient sentence that front-loads the primary action and context. It avoids unnecessary words and conveys the core purpose quickly. However, it is arguably too brief given the tool's complexity, but conciseness is about economy of language, which it achieves.

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 the tool has 8 parameters, no output schema, and no annotations, the description is severely incomplete. It does not explain the pipeline context, what each parameter means, what the output looks like, or any prerequisites. An agent would have little idea how to construct a valid call or interpret results. The description is insufficient for correct usage.

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?

The input schema has 100% description coverage, but each parameter description is simply the parameter name (e.g., 'Model' for 'model'), adding no semantic value. The tool description itself does not elaborate on any parameters, leaving the agent to infer meanings from names like 'model', 'states', 'variants', which are ambiguous. The description fails to compensate for the schema's lack of meaningful detail.

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 states a clear action: 'Create stylesheet-backed component code' and specifies the input context: 'from an approved design direction' and the pipeline position 'pipeline step 3'. This distinguishes it from design-focused siblings like coeus_frontend_design_brief and coeus_frontend_taste_direction, which produce design artifacts rather than code. However, it does not explicitly name any sibling alternatives, so it's clear but not fully differentiating among code-generation tools like coeus_generate_tests or coeus_refactor_code.

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 phrase 'pipeline step 3' hints at a sequential workflow but does not explain what precedes or follows it, nor does it state when to use this tool versus others. There is no explicit mention of when not to use it or what conditions must be met (e.g., having an approved design direction). This leaves the agent with minimal guidance on selection.

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