Function tableNameMatches

backend/api/mcp/tool_schema.go:503–518

tableNameMatches returns true if `name` is a plausible candidate for a typo of `missing`. A name matches if it contains the input as a (case-insensitive) substring, or if it shares a sufficiently long common prefix (useful for typos like "orderz" → "orders", "order_items").

// substring, or if it shares a sufficiently long common prefix (useful for typos
// like "orderz" → "orders", "order_items").
func tableNameMatches(name, missing string) bool {
	n := strings.ToLower(name)
	m := strings.ToLower(missing)
	if m == "" {
		return false
	}
	if strings.Contains(n, m) {
		return true
	}
	// Require a shared prefix of at least 4 chars (or the full input if shorter).
	prefixLen := min(4, len(m))
	if len(n) < prefixLen {
		return false
	}
	return n[:prefixLen] == m[:prefixLen]
