update_snippet

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

With no annotations, the description must convey behavioral traits but only states 'Update an existing code snippet.' It does not disclose if partial updates are supported, how missing optional fields are handled, or any side effects. This lack of transparency could lead to misuse.

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, very short sentence. While not verbose, it is too minimal and omits important details. It could be expanded slightly without losing conciseness.

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?

For a tool with six parameters and no output schema, the description lacks completeness. It does not explain the update behavior (e.g., overwrite vs. merge), return value, or error states. The presence of many sibling tools highlights the need for more context to avoid confusion.

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 coverage is 100%, so all parameters already have descriptions in the schema. The tool description adds no further meaning (e.g., constraints, formatting). Baseline 3 is appropriate as the schema does the work, and the description offers no extra param context.

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 action ('Update') and the resource ('existing code snippet'), which is specific. However, it does not differentiate this tool from siblings like create_snippet or delete_snippet, leaving the agent to infer usage from the name alone.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., create if the snippet doesn't exist, delete to remove). There is no mention of prerequisites or context, leaving the agent without clear decision points.

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