B3.1/5.0
Behavior2/5

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

The destructiveHint=true annotation already tells the agent this is a mutation, so the description should add what destruction means here — irreversibility, whether the tape's slot is freed, whether it affects overlapping obstacles. Instead it only restates 'remove ... by id', adding no behavioral context beyond the annotation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One short sentence with the key parameter and the lookup hint front-loaded, no filler. It is terse to the point of leaving gaps, but nothing in it is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive, no-output-schema tool the agent still lacks the essentials: confirmation/return behavior, reversibility, and what happens to the floor cell after removal. The lookup hint alone is not enough to call this safely and correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

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 burden for the single 'id' parameter. It does add real value by pointing to list_world as the source of valid ids, but it never states the id format or what happens on an invalid id.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Remove') and resource ('floor tape') plus the keying parameter ('by id'), which cleanly separates it from the sibling add_color_tape. It stops short of explicitly naming the inverse sibling, but the intent is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The parenthetical '(see list_world)' gives a concrete prerequisite for obtaining the id, which is useful implied guidance. However, there is no statement of when to use this versus other world-mutating siblings, nor any exclusions or preconditions.

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