pika_build_brand

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

No annotations are present. The description indicates creation of multiple brand assets but does not disclose whether the tool is stateful, requires authentication, or has any side effects. For a generative tool, this is vague.

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 action ('Generate a complete brand identity') and lists key outputs. Every word serves a purpose without redundancy.

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 single parameter and presence of an output schema, the description covers the basic intent. However, it omits usage context, parameter clarification, and behavioral notes, making it merely adequate.

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 only parameter 'brief' has no schema description (0% coverage). The description mentions 'product brief' but does not explain required format, content, or length, leaving ambiguity for the agent.

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 explicitly states it generates a complete brand identity from a product brief, listing components like strategy and tone of voice. However, it does not differentiate from sibling generative tools like pika_generate, which could perform similar tasks.

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 guidance is provided on when to use this tool versus alternatives. The description implies usage from a product brief but offers no exclusions or comparisons to siblings.

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