Behavior4/5

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

Discloses permanent deletion (cannot be undone) and absolute path requirement. With no annotations, this adds important behavioral context, though error behavior is not covered.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Extremely concise: one line purpose, example JSON, two key warnings. No wasted words, information front-loaded.

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

Completeness4/5

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

Covers purpose, usage, and security. For a delete operation with 3 params and no output schema, this is sufficient, though missing error handling or prerequisite guidance.

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

Parameters4/5

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

Schema already describes parameters well (100% coverage). Description reinforces with example and clarifies default for isDirectory, adding moderate value beyond schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clear statement 'Delete file or directory on remote host via SFTP' with specific verb and resource. Distinct from sibling tools like sftp_download or sftp_upload.

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?

Provides security warning and path requirement, but no explicit guidance on when to use vs alternatives (e.g., sftp_list_directory for confirmation). Implied usage only.

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