Start a Senior Dev in a Box session

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

No annotations are present, so the description carries the full burden. It discloses that the tool classifies the user by experience level and AI tool and returns the first interview question, but it does not clarify session persistence, duplicate-session handling, or other side effects of 'beginning' a session.

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?

Three short sentences, front-loaded with purpose and ending with the operational instruction to call it first. There is no filler, redundancy, or unnecessary detail.

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 two-enum-parameter tool, the essential call sequence, classification behavior, and return value are all stated. It lacks output-shape or session side-effect details, but the tool's simplicity keeps this gap small.

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?

Both parameters are fully documented in the schema with enums and descriptions, so the baseline is 3. The description adds only a light behavioral mapping—parameters are used for classification—which does not materially enhance what the schema already provides.

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 concrete action ('Begin a new guided project session') and adds exactly what it returns ('the first interview question'), making it clear what the tool does. The phrase 'Call this before anything else' also distinguishes it from session-retrieval, listing, and Q&A siblings.

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?

Provides a strong ordering rule: 'Call this before anything else,' which tells an agent exactly when to invoke it. However, it does not explicitly name alternatives or state when not to use it, such as when continuing an existing session.

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