Learn from an Elementor export

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

No annotations are provided, so the description carries the full burden. It discloses that the tool mutates state by merging into a persistent registry, and specifies input options. Mutation is clearly stated, and no contradictions exist.

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?

Two concise sentences: the first defines the core function, the second adds usage context and input options. No wasted words, front-loaded with the key action.

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 2-parameter tool with no output schema, the description adequately explains the process (ingest, extract, merge) and the effect (registry update). References get_widget_schema for retrieval. Slightly light on return value but acceptable.

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 100% (both parameters are described in the schema). The description adds 'Provide a file path OR the JSON inline' which repeats the mutual exclusivity already implied by the schema, adding minimal new meaning.

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 verb 'Ingest' and the resource 'Elementor JSON export', and distinguishes itself from siblings like get_widget_schema by explaining that this tool feeds data into that one.

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?

Explicitly says 'Use this to teach the server the exact shape of widgets/settings not yet known' and mentions the follow-up tool get_widget_schema, implying when to use it. No explicit when-not or alternatives, but clear enough.

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