create_schematic

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

With no annotations, the description bears the full behavioral burden. It reveals only that it returns a dictionary with a success status, which the output schema already covers. It omits whether an existing schematic of the same name is overwritten or errors, what permissions are needed, and any side effects — all material for a mutation tool.

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 purpose is front-loaded in the first sentence, which is good. But the Args/Returns/Examples doctest boilerplate is largely redundant — the Returns block restates the output schema and the example adds no information an agent needs to invoke the tool.

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 one-parameter tool with an output schema, the return-value explanation is unnecessary and the schema already defines the single input. What is missing is error/failure semantics and the relationship to sibling management tools, so it is adequate but incomplete.

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?

Coverage is 0% and there is a single parameter, so the description must carry meaning. 'name: Project name for the schematic' adds only a thin gloss beyond the schema's bare string type; it does not clarify naming constraints, uniqueness, or path semantics. Minimal but non-zero compensation.

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?

States a specific verb and resource: 'Create a new blank KiCAD schematic.' The word 'blank' usefully hints it differs from load_schematic, and the action is unambiguous. However, it does not explicitly name or differentiate itself from the other schematic-level siblings (load_schematic, save_schematic) that an agent must choose between.

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 when-to-use guidance, no preconditions, and no mention of the alternative tools. An agent is left to infer that this is the entry point for a new project versus load_schematic for an existing one. There is nothing about overwrite behavior or when creating would fail.

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