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

With no annotations, the description carries full burden and does an excellent job: it discloses the OAuth flow steps, the specific scopes requested, and the caveat that listings_w alone does not enable write operations unless the environment variable is set. It also mentions secure local storage of tokens.

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 three sentences, front-loaded with the main verb and resource, and every sentence adds value: the flow, the scopes, and the write-enablement caveat. No waste or fluff.

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?

For a login tool with no parameters and no output schema, the description covers all essential context: the authentication mechanism, the scopes requested, and a critical configuration note for write operations. It is complete enough for an agent to select and invoke the tool correctly.

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 tool has zero parameters, so the baseline is 4. The description adds no parameter-specific info (not needed), but it does provide relevant context about scopes and environment requirements, which is useful for understanding the tool's behavior.

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's purpose: it starts the OAuth-2.0 login with PKCE, detailing the flow (opens authorization page, receives callback, checks state, stores tokens). This is specific and distinguishes it from sibling tools like etsy_auth_status and etsy_auth_logout.

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 when to use the tool (for logging in) and provides important context about enabling write functionality via ETSY_WRITE_ENABLED=true. However, it does not explicitly mention alternatives or when not to use it, though this is fairly obvious given its role.

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