Beep Boop MCP

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

With no annotations provided, the description carries full burden. It discloses key behavioral traits: atomic operation (implies transactional safety), file system changes (removing and creating files), and signaling purpose. However, it lacks details on permissions, error handling, or side effects beyond clearing the directory.

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 front-loaded and concise with two sentences that efficiently convey the core action and purpose. Every sentence adds value without redundancy, making it easy to parse.

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 no annotations and no output schema, the description provides adequate context for a tool with 3 parameters and clear file operations. It covers what the tool does and why, but lacks details on return values or error conditions, leaving some gaps for an agent.

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 all parameters well. The description adds no parameter-specific semantics beyond implying 'directory' is where files are manipulated, which is redundant with schema. Baseline 3 is appropriate as schema does the heavy lifting.

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 ('removing the boop file and creating a beep file') and resource ('directory'), explaining it 'atomically completes work'. It distinguishes from siblings like 'create_beep' and 'update_boop' by combining both actions, but doesn't explicitly contrast them.

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 ('signals that work is complete and clears the directory for new work'), suggesting when to use it, but doesn't provide explicit guidance on when not to use it or name alternatives like 'create_beep' or 'update_boop' for partial operations.

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