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

No annotations are provided, so the description carries full burden. While it describes what the tool checks (collision detection), it doesn't disclose behavioral traits like what permissions are needed, whether it's read-only or has side effects, rate limits, or what the output format looks like. For a validation tool with zero annotation coverage, this is a significant gap.

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 a single, well-structured sentence that efficiently communicates the tool's purpose without any wasted words. It's appropriately sized and front-loaded with the key information.

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 the tool's moderate complexity (validation operation with 2 parameters) and no output schema, the description provides adequate context about what the tool does but lacks information about return values, error conditions, or behavioral constraints. It's complete enough for basic understanding but has clear gaps.

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 100%, so the schema already documents both parameters ('symbol_id', 'target_name') adequately. The description adds context about what these parameters represent in the collision detection process, but doesn't provide additional syntax or format details beyond what the schema provides.

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 with specific verbs ('Pre-rename collision detection', 'checks') and resources ('symbol's own file', 'all importing files', 'existing symbols with the target name'). It distinguishes from siblings like 'apply_rename' by focusing on validation rather than execution.

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 context ('Pre-rename') suggesting it should be used before performing a rename operation. However, it doesn't explicitly state when not to use it or name specific alternatives like 'apply_rename' for the actual rename operation.

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