ha_create_helper

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

The description only states the creation action with no details on side effects, permissions, constraints (e.g., maximum helpers), or error states. Since annotations are absent, the description should provide more behavioral context.

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 sentence that efficiently conveys the purpose. It could benefit from a structured list of helper types, but it remains concise and front-loaded.

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?

The description is sufficient for a creation tool with a well-documented schema, but misses contextual details like return values, error handling, or validation. For moderate complexity, it is adequate but not complete.

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 input schema already provides detailed documentation for the 'config' parameter, covering various domains. The tool description lists helper types and states config varies, adding minimal extra meaning beyond the schema's 100% coverage.

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 identifies the action (create) and resource (input helper), with a specific list of helper types. It distinguishes from sibling tools like ha_update_helper and ha_delete_helper by using 'create' and listing types.

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 on when to use this tool versus alternatives like ha_create_area or ha_create_automation. The description does not indicate prerequisites, conditions, or when not to use it.

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