brand_brandcode_auth

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

No annotations are provided, so the description carries full behavioral burden. It explains each mode's action, recommends 'activate', details the device code flow with polling, and lists alternatives. It stops short of describing error behavior or security details, but overall transparent.

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 coherent paragraph with no redundancy. It front-loads the main purpose, then details modes, usage scenarios, and exclusions. While efficient, it could be slightly more scannable with bullet points, but still earn each sentence's place.

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 4 parameters, no output schema, and no annotations, the description covers the tool's functionality well: all modes, when to use them, and what each does. It lacks details on return values or error handling, but for an auth tool, the behavioral coverage is sufficient.

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 covers all 4 parameters with descriptions (100% coverage). The description adds value beyond the schema by explaining the recommended mode, the short code format, and the purpose of each mode. For example, 'activate' is explained as preferred with an example.

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 clearly states the tool activates Brandcode Studio connection for saving brands. It lists specific modes and distinguishes from other tools by noting auth is unnecessary for extraction, preview, or brand_check. This effectively differentiates it from siblings like brand_brandcode_status or brand_brandcode_sync.

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 explicitly says when to use (e.g., user wants to save brand, says 'activate' or 'connect to Brandcode') and when not needed (extraction, preview, brand_check). It does not directly compare with sibling tools like brand_brandcode_connect, but provides clear usage context based on user intent.

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