Create Power_feed

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

Annotations already indicate this is a non-readOnly, non-destructive, non-idempotent mutation. The description adds context by noting that 'available_power' is computed and read-only in responses, and states that it adds a new row. This provides some additional behavioral insight, but the overall transparency is moderate.

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 very concise with 4 sentences. It front-loads the purpose, includes a key usage instruction, highlights a read-only field, and specifies return formats. Every sentence serves a clear purpose without redundancy.

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?

Given the tool's complexity (17 parameters, many optional) and lack of output schema, the description covers the basics: purpose, dry-run caution, read-only field note, and return format. However, it omits prerequisites (e.g., power panel ID must exist) and does not explain defaults or potential errors. The description is adequate but not thorough.

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 description coverage is 71%, so most parameters already have descriptions. The description adds value by clarifying that 'available_power' is not an input parameter (appears only in responses). This is helpful but limited. Overall, the description does not significantly enhance parameter understanding 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 clearly states 'Create a new power_feed' with a specific verb and resource. It is unambiguous about the tool's action, though it does not explicitly differentiate from sibling update or delete tools. The title and description together make the purpose clear.

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 advises asking the user if they want a dry-run before calling, which is a useful precaution. However, it does not provide guidance on when to use this tool versus other power feed tools (e.g., update or list) or alternatives. The guidance is partial.

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