B3.2/5.0
Behavior3/5

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

With no annotations, the description carries the burden, and it does disclose the key destructive trait: the current episode is discarded. However, it says nothing about irreversibility, permission requirements, or what 'blank canvas' means for prior state, leaving meaningful behavioral gaps for a destructive operation.

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?

A single front-loaded sentence with no filler; the action is stated first and the optional argument second. Slightly metaphorical phrasing ('blank canvas') costs a little precision but costs no space.

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

Completeness3/5

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

An output schema exists, so return values need not be described, and the core action is conveyed. Still, for a destructive reset with zero annotation coverage, the missing seed semantics and reversibility/precondition details leave the definition thinner than the operation warrants.

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

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must compensate. It loosely gestures at the 'task' parameter ('optional structured task specification') but gives no shape, format, or examples, and the 'seed' parameter is entirely unexplained despite being directly relevant to reproducibility of a reset.

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 and effect ('Discard this episode and start a blank canvas'), which is clearly distinct from the read-oriented siblings get_canvas_state and get_current_reward. It does not name a sibling explicitly, but the reset semantics are 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?

Usage is implied (start a fresh episode) rather than stated as an explicit trigger, and there is no guidance on when NOT to reset or what precondition must hold before discarding the current episode. Adequate but leaves the agent to infer the calling context.

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