Code Quality

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

Annotations already set readOnlyHint=false and destructiveHint=false. The description adds that the tool is fast (<1s) and finds hidden issues, but does not explain the modify-in-place behavior or potential side-effects beyond preserving side-effects. It adds some value but not extensive.

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?

Extremely concise: two short lines that front-load the action and rationale. No wasted words. Every sentence adds value.

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?

Given 3 parameters, no output schema, and sibling tools like refactoring, the description covers purpose and when-to-use but lacks parameter documentation and return value info. It is somewhat incomplete for an agent to fully understand usage.

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?

Schema description coverage is 0%, so the description must compensate. The description mentions operations (fix all, organize imports, remove unused) which map to the operation enum, but does not explain the filePath or preview parameters. Without these, an agent may not use the tool correctly.

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 states the tool's purpose: fixing TypeScript errors, organizing imports, and removing unused code. It uses specific verbs and resources. However, it could better distinguish from sibling tools like refactoring, which might have overlapping capabilities.

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?

Explicit usage guidance is provided: 'Use when: After refactoring or before commits. Use proactively.' This helps the agent decide when to invoke. It also compares to manual process. No explicit when-not to use, but the context is clear.

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