load_schematic

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 says what happens on success but discloses nothing about whether loading replaces any currently open schematic, whether it mutates on-disk state, what permissions or file-access requirements exist, or how errors are surfaced.

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 one sentence, and the Args/Returns/Examples blocks are compact and well-structured. The example is somewhat redundant but not wasteful given the low schema coverage.

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?

An output schema exists, so return-value explanation is not required, and the description's mention of project_name in the example is a useful hint. However, for a state-changing load operation with no annotations, the description omits error behavior and any interaction with previously loaded data.

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 coverage is 0% and the schema types file_path only as a string, so the description meaningfully adds that it must be an absolute path to a .kicad_sch file. That is the key detail an agent needs to construct the call correctly.

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 (load) and resource (existing KiCAD schematic file), which an agent can distinguish from create_schematic and save_schematic. It stops short of explicitly contrasting with those siblings, but the purpose is 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?

There is no statement of when to use this tool versus create_schematic or save_schematic, nor any prerequisite or ordering guidance. The usage context (load before manipulating components) must be inferred from the surrounding sibling set.

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