jules_setup_wizard

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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It mentions 'interactive session' and 'automated...configuration' but doesn't disclose critical traits like whether this initiates authentication flows, requires user interaction, handles errors, or affects existing sessions. For a setup tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 core purpose ('interactive session setup wizard') without unnecessary elaboration. Every word contributes directly to understanding the tool's function, making it appropriately sized for its complexity.

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 setup/configuration tool with no annotations, no output schema, and incomplete parameter documentation, the description is inadequate. It doesn't explain what the tool returns, how it interacts with users or systems, or what happens after configuration. Given the complexity implied by 'interactive' and 'automated', more context is needed for effective use.

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 50%, with the 'environment' parameter well-documented but the 'preferences' object lacking descriptions for its nested properties. The description adds no parameter-specific information beyond what's in the schema, failing to compensate for the coverage gap. However, with only 2 parameters total, the baseline remains moderate.

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 as an 'interactive session setup wizard for automated Google authentication configuration' with specific verbs ('setup wizard', 'configuration') and resource ('Google authentication'). It distinguishes from siblings like jules_get_cookies or jules_session_info by focusing on setup/configuration rather than retrieval or information display.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., when authentication is needed), exclusions, or comparisons with sibling tools like jules_set_cookies or jules_session_info. The agent must infer usage from the purpose alone.

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