lambda_delete_function

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action without mentioning irreversibility, permissions required, behavior on non-existent functions, or any associated resource cleanup. For a destructive operation, 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, focused sentence with no filler words. It is front-loaded with the action and resource, and every word contributes to the meaning. This is an example of efficient, concise writing.

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 simple delete tool with one parameter and no output schema, the description conveys the core purpose adequately. However, it omits important behavioral details such as error handling, idempotency, and side effects, which are particularly relevant for a destructive operation. It is minimally sufficient but leaves 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?

The schema already fully describes the single parameter 'functionName' as 'Function name or ARN' (100% schema description coverage). The description adds no extra parameter-level meaning, so it meets the baseline of 3 without adding value beyond the schema.

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 uses the specific verb 'Delete' and the resource 'Lambda function', clearly distinguishing it from sibling tools like lambda_create_function, lambda_get_function, and lambda_invoke. The phrase 'from LocalStack' adds environmental context, making the tool's scope unambiguous.

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 the tool is used to delete a Lambda function but provides no explicit guidance on when to prefer it over alternatives (e.g., update, disable) or any preconditions. The purpose is self-evident, but there is no mention of when not to use it or related actions, leaving the guidance at an implied level.

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