get_kicad_binary_path

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

No annotations are provided, so the description carries the burden. It discloses one useful behavioral detail: '.exe' is assumed on Windows, implying platform-specific path resolution. It says nothing about whether the binary is guaranteed to exist, whether installation is required, or any error behavior.

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?

One sentence plus a compact Args block; the core purpose is front-loaded and every line earns its place. No filler.

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 trivial path-lookup utility with an output schema present, the description covers what the tool does and the one non-obvious parameter behavior. It is nearly complete; only a note on failure/absence of the binary would improve it.

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?

With one parameter and 0% schema description coverage, the description has to compensate, and it does: it defines binary_name as a 'short binary name' and explains the implicit '.exe' suffix behavior on Windows. The schema supplies the default value ('kicad-cli'), so the combination is adequate.

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: returns the full path to a bundled KiCad binary, with a concrete example ('kicad-cli'). It does not, however, differentiate itself from siblings like kicad_status or run_kicad_cli, which an agent might confuse it with.

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 indication of when to call this versus alternatives, nor any prerequisites or workflow context. The agent must infer that this is a utility for locating the CLI executable before running it.

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