Complete a contest workspace

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

The description aligns with the destructiveHint and readOnlyHint annotations and adds the target state 'completed.' It does not explain side effects, reversibility, or permissions, but the annotations already signal that this is a destructive mutation.

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?

A single focused sentence with no filler. The key action and object are front-loaded, making it easy to scan.

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 one-parameter mutation tool, the description plus destructive annotation covers the basic operation. However, it omits when to use it versus generic workspace_action/contest_action, and with no output schema it does not indicate what the caller should expect after completion.

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 no parameter descriptions (0% coverage), and the description adds no information about workspace_id or how it should be used. The parameter name is somewhat self-explanatory, but the description itself provides no semantic value beyond the schema.

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 states a specific action ('Closes') and resource ('contest workspace') with the resulting state 'completed.' It is clear, though it does not explicitly contrast with sibling tools like workspace_action or contest_action.

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?

There is no guidance on when to prefer this tool over alternatives such as workspace_action or contest_action, nor any preconditions or exclusions. The agent must infer usage primarily from the tool name.

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