descend

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

No annotations are provided, so description carries full burden. It mentions a constraint (max floor) but does not disclose side effects (e.g., state changes), error conditions, or whether it's safe.

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 very short (two sentences), but one sentence is flavor text. It is concise but could be more structured, e.g., separating usage from constraint.

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?

No output schema or annotations exist. The description does not explain return values, prerequisites, or error states, leaving significant gaps for an action that alters game state.

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 input schema has one parameter with 0% coverage, so description must compensate. It adds meaning by explaining the floor parameter's range ('up to max_floor_cleared+1'), which is critical for correct usage.

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 indicates the tool is for entering the dungeon and descending to floors up to a limit, which is distinct from general movement (sibling 'move'). Some flavor text ('You remember the way') does not obscure purpose.

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 usage for floor progression and states a constraint (max_floor_cleared+1), but does not explicitly compare to alternatives like 'move' or indicate 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.
