pkg/tooldiscovery/search.go:25

• The constant parameterMatchScore is defined but never used in the actual code (the only usage is in commented-out code). This should be removed to avoid confusion, or the parameter matching functionality should be implemented if it's intended.

	parameterMatchScore   = 1

pkg/tooldiscovery/search.go:50

• The Search function passes nil as the tools parameter to SearchTools, which will result in iterating over a nil slice (lines 70-78 in SearchTools). This means Search will always return an empty result. This appears to be incomplete implementation - you should either load tools from a cache/inventory here or document this as a placeholder for future implementation.

func Search(query string, options ...SearchOptions) ([]SearchResult, error) {
	return SearchTools(nil, query, options...)

Love it, one documentation bit about the fact most people have the docker version.

[SamMorrowDrums]

I guess should maybe document the others in a follow-up. Also might be worth providing a docker run command? As most users don't have binary hanging around.
