unlink

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

No annotations provided. Description discloses symmetric behavior with link() and file path acceptance. But lacks details on destructiveness, side effects, or error conditions.

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: one sentence plus parenthetical. Front-loaded function signature. No wasted words.

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?

Output schema exists, but tool is a mutation with no annotations. Description fails to mention prerequisites, exact behavior, or what 'disconnect' entails. Incomplete for a mutation tool.

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?

With 0% schema coverage, description must compensate. It explains a, b, and action (default, 'flow') but omits 'help' parameter. Adds some meaning but incomplete.

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?

Description states 'disconnect two items' which is a specific verb+resource. However, it does not differentiate from sibling tools like 'rm' or 'cleanup' that might also remove connections.

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?

Mentions symmetry with link() and action defaults, implying when to use versus link. But no explicit exclusions or guidance on alternatives among siblings.

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