start_oauth_token_flow

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

With no annotations, the description must disclose behavioral traits. It mentions Playwright and in-memory storage, but lacks details on browser requirement, user interaction, redirect handling, or side effects. This is insufficient for an auth-flow tool.

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, concise but overly brief. It could include more essential information without becoming verbose.

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?

The tool has an output schema, but the description does not explain what it returns. Given the complexity of an OAuth flow, the lack of information about process steps, return values, and interaction with browser leaves the agent underinformed.

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 coverage is 0% and the description does not mention the only parameter (timeout_seconds) or its semantics. The description adds no value beyond the schema, which is already minimal.

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 starts an OAuth Authorization Code + PKCE flow using Playwright and stores tokens in memory. It distinguishes from siblings like refresh_oauth_token and clear_runtime_tokens, though it could be more specific about the target service.

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 explicit guidance on when to use this tool versus alternatives like refresh_oauth_token or use_browser_session_token. The description implies initiation of an OAuth flow but omits prerequisites or when not to use.

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