coeus_frontend_design_brief

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not state whether this tool mutates state, requires authentication, or has side effects. It also does not explain what happens after creation or how the brief is stored or returned. For a tool that creates something, this is a significant transparency gap.

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 sentence with no wasted words, and it front-loads the core action ('Create a frontend design brief'). The pipeline context is useful and compact. It could be slightly more structured, but it is appropriately sized.

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 7 parameters, no annotations, and no output schema, the description is too thin. It does not explain what the tool returns, how the brief is used downstream, or what distinguishes it from the many sibling design/review tools. An agent would struggle to know exactly what to pass and what to expect back.

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%, so the schema already documents all 7 parameters. The description adds no parameter-level meaning beyond the schema, but the baseline of 3 applies because the schema does the heavy lifting. The description's mention of 'taste direction, components, and assets' loosely maps to some parameters but does not clarify their semantics.

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 'Create a frontend design brief; pipeline step 1 before taste direction, components, and assets' identifies a specific verb and resource, and hints at its position in a pipeline. However, it does not clearly distinguish this from sibling tools like coeus_frontend_taste_direction or coeus_design_review_bundle, and the phrase 'pipeline step 1' is vague about what the tool actually produces.

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 description implies this is the first step in a frontend design pipeline, which gives some context for when to use it. But it does not explicitly state when not to use it or name alternative tools for related tasks, such as coeus_project_intake or coeus_design_review_bundle. The guidance is implied rather than explicit.

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