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

Annotations declare readOnlyHint=true and idempotentHint=true, yet the description says the tool will 'create the instruction-only ZIP' and 'continue in that folder', which implies filesystem artifacts and state changes. This directly conflicts with the no-side-effects claim, matching the Annotation Contradiction pattern.

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?

Two short clauses, front-loaded with the action and immediately followed by the sequencing cue and the outcome. No filler or repetition of the title/name.

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 workflow-entry tool with no output schema, the description does convey the sequence of what happens (interview, produce ZIP, continue in the folder). But it omits any parameter guidance and, more importantly, never addresses the side-effect profile that its own annotations deny.

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 0%, so the description carries the full burden of explaining the two parameters, and it mentions neither 'client' nor 'language'. The enums in the schema give the allowed values, so an agent can still supply them, but the description adds no semantics about defaults or intent.

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 names a specific verb+resource ('Start the guided Website Starter workflow') and implies ordering with 'Use this first', which distinguishes it from siblings like describe_starter/get_starter. It stops short of naming any sibling explicitly, so differentiation is inferential rather than stated.

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?

'Use this first' is an explicit sequencing instruction that tells the agent this is the entry point rather than one of the sibling starters. It does not name the alternatives (create_starter, describe_starter, get_starter) or state when NOT to use it, so the guidance is clear but not exhaustive.

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